Medical Instruments and Equipment of a Cardiologist

Updated on July 31, 2012

Diagnosing and treating sick or injured patients will never be easy if health care professionals will have no medical instruments at their side. Medical instruments are considered as a part of health technologies that facilitate medical specialists to effectively and efficiently perform their functions.

The medical instruments and equipment that we often seen in the hospitals are varied and each of them are designed for specific specialty. And today, what I am going to share to you are some of the essential medical instruments being used by cardiologist whenever we have to consult to them the condition of our heart.


This is the standard medical instrument used to measure blood pressure. The device is often used in conjunction with a stethoscope. Sphygmomanometer often comes with an inflatable cuff with a meter, which is then attached around the patients arm over the brachial artery. Aside from sphygmomanometer, other forms of medical instruments that can be used for BP monitoring are the digital or electronic ones.


The stethoscope on the hand will be used to listen to the sounds as the blood begins to flow through the artery while the cuff is deflated. Medical specialists of the heart know that when it comes to stethoscope, nothing is better than littmann cardiology stethoscopes. This particular device for auscultation is much better than conventional ones because it allows cardiologists to conveniently alternate low and high frequency sounds without needing to turn over the chestpiece.

Arterial Tonometry

This medical instrument often comes with a sensor that allows cardiologist to easily monitor arterial stiffness. It is vital to check the stiffness of arteries because it helps predict the possibility of future cardiovascular events like heart attack and stroke.

Cardiovascular Magnetic Resonance Imaging (CMR)

It is a specialized magnetic resonance imaging for the heart that makes use of ECG for gating. This medical equipment likewise allows cardiologist to view the mechanical functions of the heart.

Electrocardiogram Machine

It is a special type of ultrasound machine that enables cardiologist to examine the pumping ability of the chambers and valves of the heart as well as the blood flow.

Heart Monitoring Patch

This is one of the most portable medical instruments used for monitoring the condition of the heart. Heart monitoring patch is very thin in appearance comes with a sensors and other electronic components that facilitates in monitoring the said organ. To use this device, it is simply mounted onto the skin just like a temporary tattoo.

ECG Machine

The electrocardiography machine is purposely created to monitor the electrical impulses of the heart, typically with 4 or 10 electrodes on the skin. Through this machine, the cardiologist is able to determine the heart rate, the heart rhythm, the condition of heart muscle, if there are conduction abnormalities, if there is a coronary artery disease, or if there has been a previous heart attack.

Pulse Oximeter

It is an external probe that utilizes light bounced off the blood vessel. The pulse oximeter is designed to indirectly monitor the oxygen saturation of the blood. The pulses of blood with the heart rate are likewise determined by this medical device.

      This is like a crash course in common medical equipment. It is helpful to those who don't have very much medical knowledge. Nicely done.

      Very informative hub..You obviously extend yourself in your broke it down so it helps "joe layman" better understand when these tests are ordered,and patients feels more comfortable.I am retired from Medical Field and always felt this issue was important in communicating with patients.KUDOS....Good job !
