best cardiology stethoscope

Stethoscopes transformed medical practice through non-invasive internal auscultation. Auscultation through the stethoscope is a vital skill in any physician’s diagnostic arsenal, but for cardiologists it forms the most important initial investigation.

Cardiology stethoscopes deliver significantly superior acoustic performance and diagnostic versatility in comparison to generic stethoscopes. The improved acoustic quality allows for easier differentiation of high and low frequency sounds – a particularly important feature in differentiating heart sounds – while enhanced tubing minimizes noise artefact. For these reasons, many clinicians outside of cardiology opt to invest in a cardiology-grade stethoscope, which prove invaluable in any field of medicine.

We’ve compiled a list of the best cardiology stethoscopes, chosen and reviewed by our medical professionals, to help you choose the best cardiology stethoscope that fits your needs.

What to Look for in a Stethoscope

Parts of the Stethoscope

Most stethoscopes have the following parts:

Low-cost stethoscopes only offer the basic version of these parts while higher-end acoustic stethoscopes will have a wider variety in parts.

 1.  Earpieces

Earpieces can be either soft or rigid and they come in several sizes.

If possible, you should choose a stethoscope that comes with interchangeable earpieces.

This is an important feature for settings where a stethoscope is used a lot like internal medicine offices, cardiology practices, intensive care units and for emergency rooms.

Preferably, the earpiece angle should be adjustable which allows different user the ability to customize the headset so that it fits their own ears comfortably.

Some stethoscopes are able to reduce ambient noise, which is great for healthcare professional.

Examples include those that work in a noisy environment like paramedics, anesthesiologists and emergency room workers.

2.  Chest Piece

A chest piece can either be single or double headed.

A double headed chest piece has a diaphragm that allows you to hear high frequencies on one side and a bell for the low frequencies on the other side while a single headed chest piece has both on one side.

The healthcare professional can use different amounts of pressure in listening for the different frequencies.

Chest pieces are available in different sized diameters that are helpful for pediatric healthcare professionals and for those that work with patients in a variety of sizes.

Most adults work well with a 35mm size and children need a 25 mm size. For cardiac healthcare professionals, a 45 mm diaphragm works for listening for subtle heart sounds.

For all sizes, a non-chill rim is the most comfortable type for patients.

3.  Tubing Style and Length

The average tubing length is 22 to 28 inches with the longer lengths draping around a healthcare professional’s neck better and helps it to stay in place.

It also is better for keeping some distance between the healthcare provider and a sick patient.

Stethoscope tubing comes in many different colors enabling healthcare professionals some personalization although black is the most common.

Latex tubing is becoming less common due to patient latex allergies but all tubing should be flexible to avoid splitting or breakage during use.

Tubing can be either single or double bore with some tubing using the bi-lumen style where two tubes are combined into a single tube.

Bi-lumen style helps to stop the sound of the tubes rubbing together.

Wide tubes help to improve sound quality that can be helpful to emergency care providers, respiratory therapists, Intensive care practitioners and cardiologists.


Acoustic vs Electronic Stethoscopes

Acoustic stethoscopes are still the most common for most healthcare providers.

Cardiologists that need to hear heart sounds will find that the high-quality acoustic stethoscope picks up both low and high frequencies well.

Providers that cannot hear specific frequencies well may need to have the sound amplification of an electronic stethoscope that also features noise reduction.

Some electronic stethoscopes can also capture electrocardiogram data and oxygen saturation levels and can transfer the information to a computer.
