6 days ago

Here’s something that doesn’t get said enough: cardiac nurses need stethoscopes that are just as good as the ones cardiologists use. Not close — just as good.

You are managing post-op bypass patients at hour six when their pressure starts creeping down. You are the one at the bedside when a new murmur appears on a patient who didn’t have one yesterday. You are the nurse who catches the subtle change in lung sounds before the chest X-ray confirms what you already suspected. On a cardiac floor, a telemetry unit, or a step-down unit, your stethoscope is not background equipment — it is the first line of clinical intelligence, and the quality of what you hear directly influences the speed and accuracy of everything that follows.

This guide is built specifically for cardiac nurses — RNs working in cardiac care units, telemetry, cardiac step-down, post-surgical cardiac floors, and cardiac catheterization labs. We’ve reviewed the top stethoscopes on the market and matched them to the specific demands of cardiac nursing: identifying new or changing murmurs, monitoring post-operative patients, assessing fluid status, and working in noisy, fast-moving hospital environments where acoustic precision is not optional.

Below you’ll find honest, clinically grounded reviews, a quick comparison table, and a buying guide that addresses what actually matters in your unit — not a generic list written for general nurses.

Our Top Picks for the Best Stethoscope for Cardiac Nurses

1. Littmann Master Cardiology — Best Overall Stethoscope for Cardiac Nurses

If you work on a cardiac floor, a telemetry unit, or a step-down unit, this is the stethoscope that was built for your patients. The Littmann Master Cardiology is the benchmark for analog acoustic performance — and in a unit where detecting a new aortic regurgitation murmur or catching early pulmonary edema on a post-CABG patient can change a clinical trajectory, that benchmark matters.

Key Features

Single-sided pressure-tunable chestpiece with handcrafted tunable diaphragm
Adjusts between low-frequency and high-frequency sounds through applied pressure — no chestpiece flipping
Exceptional low-frequency response for S3, S4, and diastolic sounds
27-inch tubing
7-year warranty
Available with optional Satin Finish tubing

Why We Recommend It for Cardiac Nurses

The Master Cardiology’s defining feature is its pressure-tunable single-sided chestpiece. Apply light pressure and you’re in bell mode — picking up low-frequency sounds like S3 gallops, the diastolic rumble of mitral stenosis, or subtle pericardial friction rubs. Apply firmer pressure and you shift into diaphragm mode for high-frequency sounds — systolic murmurs, breath sounds, S1 and S2. You do all of this without taking the stethoscope off the chest or flipping it around.

On a cardiac floor, this is significant. When you’re assessing a post-operative valve repair patient every two hours overnight, the ability to sweep seamlessly through low and high frequencies in one smooth motion is both clinically efficient and acoustically thorough. You are less likely to miss something when the tool works with your workflow rather than against it.

The acoustic clarity on the Master Cardiology is genuinely in a class of its own among analog stethoscopes. If you’ve been working with a mid-range stethoscope and upgrade to this, the first thing you’ll notice is how much more you can hear. Subtle findings you may have been uncertain about — a soft early diastolic murmur, a faint third heart sound in a patient with decompensating heart failure — come through with a clarity that changes how confidently you communicate your assessment to the care team.

One honest caveat: the Master Cardiology has no true pediatric side. If your unit occasionally accepts pediatric cardiac transfers, you’ll want to consider the Cardiology IV instead. But for adult-focused cardiac, telemetry, and step-down nurses, this is the best stethoscope available at any price point in the analog category.

The tubing on the standard version can feel slightly stiff, particularly in colder environments. 3M offers the Master Cardiology with Satin Finish tubing — if you work long shifts and your stethoscope is constantly brushing against your scrubs, bare arms, or the hair on your neck, this upgrade is worth the added cost. The satin finish eliminates the friction and sticky pull of traditional PVC tubing entirely, which becomes noticeable and genuinely welcome by hour eight of a twelve-hour shift.

Pros

Best-in-class analog acoustic performance — 10/10
Pressure-tunable single chestpiece transitions smoothly between low and high frequencies
Exceptional for murmur identification, gallop detection, and pericardial sounds
No chestpiece flipping — maintains clinical efficiency at the bedside
7-year warranty from 3M
Available with Satin Finish tubing

Cons

No dedicated pediatric side
Highest price point among analog options on this list
Best suited to adult cardiac patients specifically

Best For

Cardiac floor RNs, telemetry nurses, step-down unit nurses, cardiac ICU nurses focused on adult patients, experienced nurses who want the absolute best analog acoustic performance

2. Littmann Cardiology IV — Best Versatile Stethoscope for Cardiac Nurses

If the Master Cardiology is the pure cardiac specialist’s tool, the Littmann Cardiology IV is the cardiac nurse’s all-around workhorse. It sits just a fraction behind the Master Cardiology in raw acoustic performance — a distinction most clinicians won’t perceive in everyday practice — but adds dual-sided versatility that makes it the better choice for nurses whose units receive a wider range of patients.

Key Features

Dual-sided adult and pediatric tunable diaphragm chestpiece
Adult side and smaller pediatric side — both pressure-tunable
Pediatric side converts to open bell by replacing the diaphragm with a non-chill rim
27-inch tubing with ambient noise reduction
7-year warranty
Available with Satin Finish tubing

Why We Recommend It for Cardiac Nurses

The Cardiology IV’s acoustic performance is exceptional — it is meaningfully better than mid-range stethoscopes and performs at a level where you can reliably detect Grade I and II/VI systolic murmurs, distinguish fine basilar crackles from referred upper airway sounds, and pick up faint S3 gallops on a fluid-overloaded heart failure patient.

The dual-sided chestpiece adds a layer of clinical utility that cardiac nurses in certain settings will find valuable. The pediatric diaphragm matters if your unit occasionally accepts younger patients or congenital cardiac cases. And the clinical pearl worth knowing: the pediatric side can be converted into an open bell by swapping the diaphragm for a non-chill rim — meaning you gain a true bell for low-frequency assessment without carrying a second stethoscope. For catching low-pitched diastolic murmurs or assessing pacemaker-dependent patients for subtle new sounds, that open bell capability is clinically useful.

For cardiac nurses who primarily see adult post-operative and telemetry patients, the performance gap between the Cardiology IV and the Master Cardiology is small enough that either is an excellent choice. The decision often comes down to whether you value the dual-sided flexibility of the IV or the single-sided precision and sweep of the Master Cardiology.

Like the Master Cardiology, the Cardiology IV is available with Satin Finish tubing — strongly recommended for the same reasons. Long shifts, constant movement, and clinical environments that are neither particularly warm nor particularly quiet make the satin finish upgrade a quality-of-life decision you won’t regret.

Pros

Exceptional acoustic performance — 9/10
Dual-sided adult and pediatric chestpiece
Pediatric side converts to open bell for low-frequency assessment
Versatile across diverse patient populations
Available with Satin Finish tubing
7-year warranty

Cons

Slightly heavier than other options on this list
Tubing can feel stiff initially before softening with use
Not quite the acoustic equal of the Master Cardiology for pure adult cardiac assessment

Best For

Cardiac nurses on mixed acuity floors, nurses whose units accept pediatric transfers, telemetry and step-down RNs who want top-tier versatility

3. Eko CORE Digital Stethoscope — Best Stethoscope for Cardiac Nurses in High-Noise Environments

The Eko CORE is the stethoscope that changes the conversation around what acoustic performance can look like. If you work on a busy cardiac floor where alarms are a constant soundtrack, where conversations happen across open bay areas, and where the HVAC system competes with everything you’re trying to hear — this is the stethoscope that takes that entire problem off the table.

Key Features

Up to 40x sound amplification
Active noise cancellation technology
Bluetooth connectivity to the Eko app (iOS and Android)
Visual phonocardiogram — see heart sounds displayed graphically in real time
Compatible with Littmann Classic III chestpiece
Records and stores auscultation clips for documentation or handoff

Why We Recommend It for Cardiac Nurses

Here’s the clinical scenario that makes the Eko CORE impossible to dismiss. It’s 2 AM on a 24-bed telemetry floor. You have a post-CABG patient in bed 6 who is tachycardic. The monitoring tech flags you. You grab your stethoscope and step to the bedside — but the patient in the next bay is agitated and the overhead paging system is running. With a traditional stethoscope, even a good one, ambient noise compromises what you’re hearing. With the Eko CORE’s active noise cancellation and 40x amplification, that ambient noise essentially disappears.

Beyond noise cancellation, the visual phonocardiogram displayed in the Eko app deserves attention from cardiac nurses specifically. Seeing heart sounds represented graphically in real time — watching S1, S2, and any additional sounds plot out visually as you auscultate — adds a layer of confidence and clarity to cardiac assessment that no analog stethoscope can match. When you’re trying to determine whether what you’re hearing is a split S2, an S3, or an early systolic click, seeing the visual representation alongside the audio is clinically meaningful.

The auscultation recording feature also has real value in cardiac nursing. Capturing an unusual heart sound, attaching it to a patient note, and sending it to the attending physician during a phone consultation is a significantly more effective communication tool than the words “there’s a new murmur I can’t quite characterize.” That kind of clinical communication strengthens the care team’s ability to respond quickly.

The trade-offs are honest. This is the heaviest stethoscope on the list, and it requires regular charging — battery management becomes part of your shift routine. The chestpiece feels bulkier than a traditional stethoscope until you adjust. And the price point is at the top end of any stethoscope list. For cardiac nurses in standard environments who don’t face persistent noise issues, a premium analog like the Master Cardiology or Cardiology IV remains the more practical daily tool. But in the right environment and for the right nurse, the Eko CORE is genuinely without equal.

Pros

40x amplification eliminates the noise problem entirely in chaotic unit environments
Active noise cancellation
Visual phonocardiogram — ideal for complex cardiac sound identification
Records auscultation clips for documentation and clinical communication
Strong tool for nurses who precept students or work in academic settings

Cons

Requires regular charging — needs to be part of your shift prep
Heaviest chestpiece on this list
App dependency for the full feature set
Significant price investment

Best For

Cardiac nurses in open-bay telemetry units, busy cardiac floors with high ambient noise, clinical preceptors, nurses with any degree of hearing difficulty, nurses in academic medical centers

4. MDF ProCardial Titanium — Best Lightweight Stethoscope for Cardiac Nurses

Twelve-hour shifts are not kind to your neck and shoulders. If you already carry tension through your upper back from a demanding floor, adding a heavy stethoscope to the equation makes a bad situation worse. The MDF ProCardial Titanium addresses this problem directly, delivering near-Cardiology IV acoustic performance in a stethoscope that weighs significantly less than its stainless steel competition.

Key Features

Titanium alloy chestpiece — strong, corrosion-resistant, dramatically lightweight
Dual-sided adult and pediatric tunable diaphragm
Handcrafted in Europe
Lifetime warranty with free parts for life program
Multiple earpiece options included in the box

Why We Recommend It for Cardiac Nurses

Titanium is the material choice that matters here. Stainless steel chestpieces on premium stethoscopes deliver excellent acoustic performance, but they carry weight — and on a 12-hour cardiac shift where you’re auscultating every patient every two hours, that weight accumulates. The ProCardial Titanium reduces that load without sacrificing meaningful acoustic quality.

The acoustic performance rates at approximately 8.5/10 — behind the Master Cardiology and very close to the Cardiology IV. In real-world clinical practice on a cardiac floor, this is a stethoscope that performs at an elite level. You will hear new murmurs. You will catch S3 gallops. You will pick up early crackles before the chest X-ray is back. The titanium construction does not compromise your clinical capability.

The lifetime warranty is genuinely exceptional and reframes how you think about the purchase. You’re not buying a stethoscope you’ll replace in five or seven years — you’re buying one you’ll keep indefinitely, with free parts replacement throughout that time. Factor that into a cost comparison against premium Littmann models and the math changes considerably.

The one consistent user complaint is that the tubing runs slightly longer than Littmann’s and has a springier feel that can cause it to bounce slightly during fast movement. It’s a minor ergonomic note, not a clinical limitation.

Pros

Significantly lighter than stainless steel competitors — reduces neck and shoulder fatigue
Acoustic performance close to Littmann Cardiology IV
Dual-sided chestpiece covers adult and pediatric patients
Lifetime warranty — exceptional long-term value
Strong alternative for nurses who prefer non-Littmann brands

Cons

Slightly longer, springier tubing that can bounce during fast movement
Less widely available in hospital supply stores than Littmann
Brand recognition lower than Littmann in clinical settings

Best For

Cardiac nurses managing neck or shoulder fatigue, long-shift nurses, experienced cardiac RNs looking for a high-performance Littmann alternative

5. Littmann Classic III — Best Value Stethoscope for Cardiac Nurses

Not every cardiac nurse needs a top-of-the-line stethoscope. New graduate nurses entering their first cardiac unit, nurses returning to the floor after time away, or experienced nurses who need a reliable backup option — the Littmann Classic III is the stethoscope that makes the most sense when budget is a real constraint but clinical quality cannot be compromised.

Key Features

Single-sided tunable diaphragm with open bell capability
Dual-lumen tubing
Available with Satin Finish tubing
5-year warranty
Lightweight at 132g
Over a dozen color options

Why We Recommend It for Cardiac Nurses

The Classic III is not a cardiology-grade stethoscope in the same tier as the Master Cardiology — and it doesn’t pretend to be. What it is, is a legitimately competent clinical tool built on the same core Littmann tunable diaphragm technology found in the rest of the lineup. For a cardiac nurse doing routine assessments — hourly heart and lung sounds, routine cardiac monitoring, blood pressures by auscultation — the Classic III delivers reliable performance that will not let you down.

The primary limitation on a cardiac floor is sound isolation in noisy environments. Busy telemetry units, open nursing stations, and high-traffic floors can compromise the Classic III’s acoustic performance in a way that a Cardiology IV or Master Cardiology would handle better. If you’re regularly trying to pick up subtle Grade II murmurs on a noisy unit, you may find yourself working harder than you should.

But here’s the practical reality: many experienced cardiac nurses carry the Classic III as a backup and keep a premium stethoscope as their primary. For new graduate nurses entering their first cardiac role, starting with the Classic III while you build clinical experience — then upgrading once you know your unit’s specific demands — is a completely sensible approach.

Pros

Reliable Littmann acoustic quality at a lower price point
Lightweight and comfortable for long shifts
Tunable diaphragm technology
Available with Satin Finish tubing
Great starting point for new cardiac nurses

Cons

Sound isolation less effective in noisy cardiac unit environments
Not suited for complex or nuanced cardiac auscultation in challenging conditions
A ceiling you may outgrow as your cardiac assessment skills develop

Best For

New graduate nurses starting in cardiac, backup stethoscope, budget-conscious experienced cardiac nurses in quieter unit environments

6. ADC Adscope 603 — Best Budget Stethoscope for Cardiac Nurses

There are scenarios where you genuinely need a reliable stethoscope that doesn’t cost a premium — starting a new job before your first paycheck lands, working in an environment where equipment goes missing, or picking up a backup option for a float assignment. The ADC Adscope 603 is the answer for those moments.

Key Features

Convertible chestpiece — traditional double-head or single tunable diaphragm
Full-rotation chestpiece design
Lifetime warranty
Durable build quality despite its low price point

Why We Recommend It for Cardiac Nurses

For a budget stethoscope, the Adscope 603 over-delivers. The acoustic performance — rated at 6.5 out of 10 — is functional for routine cardiac floor assessments: basic heart and lung sounds, blood pressures by auscultation, general monitoring. It won’t give you the nuanced acoustic clarity you need to confidently characterize a faint new murmur or pick up an S4 gallop in a loud environment. For that, you need to step up the ladder.

But as a backup stethoscope, a float pool option, or a starting point for a nurse who is genuinely budget-constrained, the Adscope 603 is a solid, honest choice. The lifetime warranty is a genuine differentiator at this price point and reflects ADC’s confidence in the build. The main drawback is the eartips, which are noticeably stiffer and less comfortable than Littmann’s soft-seal eartips — many nurses swap in aftermarket eartips to improve the wearing experience.

Pros

Highly affordable with surprisingly solid construction
Lifetime warranty
Functional for routine cardiac nursing assessments
Convertible chestpiece design

Cons

Acoustic performance noticeably below premium options — not ideal for subtle cardiac findings
Stiffer eartips compared to Littmann
Not suited to complex cardiac assessment in noisy environments

Best For

New nurses on a tight budget, backup stethoscope, float pool assignments, high-theft environments

Best Littmann Stethoscope for Cardiac Nurses — Which One Is Right for You?

Littmann is the dominant brand in cardiac nursing for a reason. The acoustic engineering is purpose-built for clinical use, the build quality holds up to daily hospital use, and the product line gives you genuine options depending on your setting and budget.

The Master Cardiology is the right choice if your unit is primarily adult cardiac, you manage complex post-operative and heart failure patients, and acoustic precision is your primary requirement. The single-sided pressure-tunable design is purpose-built for exactly the sounds that matter most in cardiac nursing.

The Cardiology IV is the right choice if you want top-tier performance with the flexibility of a dual-sided chestpiece — particularly useful if your unit accepts a broader patient mix or occasional pediatric cases.

The Classic III is the right choice if you’re a new graduate cardiac nurse or managing a tight budget, and you want trusted Littmann quality as your starting point before upgrading as your clinical practice develops.

All three are available with Satin Finish tubing, and for cardiac nurses working twelve-hour shifts, this upgrade is worth adding to any model. The reduction in friction against scrubs and skin throughout a long shift is one of those small quality-of-life details that becomes a big deal in practice.

How to Choose the Best Stethoscope for Cardiac Nursing

Stethoscope selection in cardiac nursing isn’t just about brand names and price points. It’s about matching a tool to the specific acoustic demands of your unit and your patients. Here’s what to think through before you buy.

Acoustic Performance Is Non-Negotiable

In cardiac nursing, acoustic performance is the single most important factor — and it’s worth paying for. The sounds that matter on your unit — an early S3 gallop in a decompensating heart failure patient, a new mid-systolic murmur on a post-valve repair patient, a pericardial friction rub in a patient three days out from a cardiac catheterization — are subtle, and they require a stethoscope capable of transmitting them clearly enough for you to trust what you’re hearing.

A low or mid-tier stethoscope may still pick up obvious findings. But when you’re trying to determine whether what you hear is clinically significant or background noise, the acoustic ceiling of your stethoscope directly affects your confidence and your ability to communicate effectively to the physician team.

Low-Frequency Sensitivity Matters in Cardiac Assessment

This is a point that is often overlooked in general stethoscope guides but is critically important for cardiac nurses. The sounds most relevant to your patients — S3 and S4 gallops, the diastolic rumble of mitral stenosis, early pericardial friction rubs — are low-frequency sounds. Standard stethoscopes that lack a true bell, or that don’t transmit low frequencies cleanly, can cause you to miss these entirely.

The Littmann Master Cardiology and Cardiology IV both excel in low-frequency transmission. The Eko CORE’s amplification makes low-frequency sounds significantly easier to detect. The classic bell function (whether through an open bell chestpiece or the bell mode of a tunable diaphragm) should be part of any cardiac nurse’s assessment routine.

The Noise Problem on Cardiac Units

Cardiac floors and telemetry units are loud. Monitor alarms, overhead paging, nursing staff activity, adjacent patient bays — all of it creates a background noise environment that works against your ability to auscultate accurately. This is not a trivial consideration.

Standard mid-range stethoscopes give you no help against ambient noise. High-end analog stethoscopes like the Master Cardiology and Cardiology IV are designed with noise-reducing tubing and chestpiece construction that provides meaningful improvement. The Eko CORE’s active noise cancellation removes the problem almost entirely.

If ambient noise has ever made you uncertain about an auscultatory finding — if you’ve ever said “I think I hear something but I’m not sure” while standing at a busy bedside — upgrading your stethoscope is likely to change that experience.

Comfort for Long Shifts

Twelve-hour shifts are the standard in cardiac nursing. A stethoscope worn around the neck continuously for that duration needs to be comfortable — not just in terms of weight, but in terms of how the tubing interacts with your skin and clothing.

The MDF ProCardial Titanium’s titanium chestpiece is the lightest high-performance option on this list. For nurses already experiencing neck or shoulder strain, it is worth serious consideration.

3M’s Satin Finish tubing, available on all major Littmann models, addresses the friction problem that standard PVC tubing creates. If your current stethoscope pulls at the back of your neck, sticks to your scrubs, or catches on your badge lanyard throughout a shift, the satin finish eliminates all of that.

Post-Operative Cardiac Patients: What Your Stethoscope Needs to Handle

Post-CABG, post-valve repair, and post-cardiac catheterization patients have specific auscultatory considerations that inform what you need from a stethoscope.

In the immediate post-operative period, you’re listening for new murmurs that weren’t present pre-operatively, checking for signs of pericardial effusion (muffled heart sounds, friction rubs), and assessing pulmonary status to catch early fluid accumulation before it becomes a respiratory crisis. These assessments demand a stethoscope with excellent low-frequency sensitivity and enough acoustic clarity to distinguish subtle new sounds from expected post-operative noise.

A stethoscope that performs at the Master Cardiology or Cardiology IV level gives you the acoustic range to make these assessments confidently. The Eko CORE’s recording capability also adds genuine value here — being able to document an unusual sound at 2 AM and send the recording to the attending with a care call is a level of clinical communication that no analog stethoscope enables.

Pacemaker and Device Patients

Cardiac nurses frequently manage patients with permanent pacemakers, ICDs, and CRT devices. While your primary monitoring for these patients comes from telemetry and device interrogation, auscultation remains important — particularly for assessing for pacemaker-associated complications like lead-related tricuspid regurgitation or post-implantation pericarditis.

Detecting subtle new murmurs on a device patient requires a stethoscope sensitive enough to catch low-grade findings in what can be acoustically complex chests. This is another clinical context that argues for investing in the best analog stethoscope you can afford, or in the Eko CORE’s digital amplification if your patient population is particularly complex.

Digital vs. Analog: What Cardiac Nurses Should Know

The analog vs. digital question comes up often, and for cardiac nurses it deserves a direct answer. Most cardiac nurses will be best served by a high-quality analog stethoscope — the Master Cardiology or Cardiology IV — for daily practice. Analog stethoscopes don’t need charging, don’t require app management, are lighter, and are immediately ready to use at any moment during a shift.

The Eko CORE tips the scales for nurses in specific situations: persistently noisy unit environments, any degree of hearing difficulty, clinical precepting roles where teaching auscultation is part of your job, and settings where documenting heart sounds as part of a care record adds clinical value. For those nurses, the Eko CORE is not just a better option — it’s potentially transformative.

Cardiac Nurse Stethoscope Buying Guide

New Graduate Cardiac Nurse

Starting your first cardiac role is not the time to show up with a stethoscope from nursing school. Cardiac patients demand more, and the faster you develop your auscultatory skills in this environment, the better you’ll become at catching subtle changes early. The Littmann Classic III is the right starting investment — it gives you genuine Littmann acoustic quality, it is affordable enough not to cause anxiety about loss or damage in your first few months, and it will serve you well as you build your baseline cardiac assessment skills. When you feel confident in your clinical ear and know your unit’s specific demands, upgrading to the Cardiology IV or Master Cardiology becomes a natural next step.

Experienced Cardiac Floor Nurse

You’ve been doing this long enough to know that what you hear matters. If you’re still working with a mid-range or entry-level stethoscope, upgrading to the Littmann Master Cardiology or Cardiology IV will genuinely change your clinical experience — not just in academic terms but in the practical, daily reality of managing complex patients. The acoustic difference between a Classic III and a Master Cardiology is not subtle. You will hear things you weren’t hearing before, and that changes how you report, how you escalate, and how confident you feel in your assessments.

Telemetry and Step-Down Nurses

Your environment is high-noise and your patients are high-complexity. This combination argues strongly for the best acoustic tool you can invest in. The Littmann Cardiology IV handles most of what telemetry demands, while the Master Cardiology gives you the edge for the cardiac-focused subset of your assessment. If your unit runs particularly loud and ambient noise consistently compromises your ability to auscultate at the bedside, the Eko CORE is worth a serious look.

Cardiac ICU Nurses

Complex cardiac ICU patients — post-LVAD, post-heart transplant, cardiogenic shock — have uniquely demanding auscultatory needs. These are patients where missing a subtle acoustic change can have immediate clinical consequences. The Master Cardiology and Eko CORE are the tools that match the complexity of the patients you manage. The Eko CORE’s visual phonocardiogram adds a layer of assessment confidence that is particularly valuable in the ICU context.

Is a Cardiology-Grade Stethoscope Worth It for Cardiac Nurses?

Without question, yes.

This is a common hesitation — the idea that a high-end stethoscope is something reserved for physicians and advanced practice providers. It isn’t. The acoustic demands of cardiac nursing — detecting new murmurs, catching early heart failure decompensation, assessing post-operative complications — are as high as, or higher than, many general clinical settings. A cardiac nurse using a cardiology-grade stethoscope is not over-equipped. They are appropriately equipped for the complexity of their patients.

A stethoscope that allows you to hear clearly and confidently is a patient safety investment. And on a cardiac floor, that investment pays for itself every time you catch something early.
