Reviews of the Best Cardiology Stethoscope


The invention of the stethoscope brought a big revolution to the world of medicine. Unlike pre-stethoscope days where doctors had to undertake harsh cumbersome procedures to diagnosis patients, this new technology presented an easy way of diagnosing by simple auscultation.

To this day, the stethoscope has remained a stronghold for physicians. In fact, some medical practitioners like cardiologists wholly rely on it to reach the organ they have specialized in.

However, with technology come some challenges:

  • What model is better than the other?
  • How to choose the best model?
  • Which alternative models can serve the same purpose?

Read on for a guide on how to choose the best cardiology stethoscope.

How to Choose the Best Stethoscope for Cardiologist

There are different brands of stethoscopes you can choose. To find the best model for you, you should read cardiology stethoscope reviews of past buyers. Here are some things to keep in mind to find a good stethoscope.

Parts of a Stethoscope

Quality acoustic stethoscopes have various parts unlike cheaper brands. The following are the integral parts of a cardiologist stethoscope.

  • The chest piece
  • Tubing
  • The ear piece

The Chest Piece

A chest piece can be either single head or double head. The double head chest piece has a bell on one side for hearing low frequency sounds and a diaphragm on the other for hearing high pitched sounds. To listen to the different sound frequencies, you have to apply some pressure to the chest piece in relation to the frequency you want to hear.

Models also come in different diameters. This is important due to the different sizes of patients you will be handling. While infants can be examined with the 25mm size, you will need the 35 mm for examining adults. The 45mm is more ideal when listening to subtle heart beats.

The non-chill rim diaphragm is recommended irrespective of the patients that you will be dealing with as it makes the patient more comfortable.

Tubing Length and Style

An average tubing length is between 22 to 28 inches. Some steths having lengths that can easily go a physician’s neck.

The tubing can either ba e single or double lumen. There are also bi-lumen tubes that combines two tubes in one. The bi- lumen tubing prevents noise interference from the rubbing of the tubes together.

Choosing a stethoscope with a reasonable tube length is important as some patients always feel intimidated when the distance between them and the clinician is small.

The wider the tube, the better the sound quality. This is useful for intensive care practitioners, emergency care providers, cardiologists and respiratory therapists.

The type of material that the tubing is made is also an important factor to consider. This is because some patients might be sensitive to some materials like latex. Also, the type and material quality will determine how vulnerable the tube is to breakages and splitting.

Although black is the most common color, some top rated stethoscope models come in an array of colors.

Ear Pieces

Ear pieces come in varying sizes and types. They can either be hard or soft. Choose stethoscopes with interchangeable earpieces.

The material used, for example, rubber or gel, can help to reduce background noises. This makes such ear pieces perfect for emergency room workers, paramedics and anesthesiologists.

In settings like cardiology units, intensive care units, emergency rooms and medicine offices, the type of ear piece can make a huge difference in your overall performance.

If you have irregular ear lobes that even adjustable ear pieces don’t seem to fit, go for customized headsets. These will also have customized ear pieces for a comfortable fit.

Acoustic vs. Electronic Stethoscope

Even today, most physicians still identify more with and prefer traditional acoustic stethoscopes.

Cardiologists  need to pick high quality acoustic stethoscopes that can tap both high and low frequency. For medics that can’t hear specific sound frequencies, maybe because they have hearing imperfections, the amplified electronic stethoscopes will be right for them. Most of the amplified stethoscopes have a noise reduction feature.

There are also electronic stethoscopes that can capture electrocardiogram data and oxygen saturation levels and transfer the information to a PC.

So, what model is the best cardiology stethoscope?

The 3M Littmann Cardiology IV Stethoscope easily scoops the medal for the best stethoscope for cardiologist. It has enhanced audibility of high frequencies and double bore tubing that eliminates noises made when the tubes rub together. This tube also comes with a one piece tunable diaphragm on both sides, which makes it ideal for examining both children and adults.

The Littmann Cardology stethoscope also has the next generation tubing. The tubing is durable and resistant to alcohol and skin oil.
