Electrocardiogram (ECG or EKG)

An electrocardiogram (abbreviated as EKG or ECG) is a test used by medical professionals to determine the electrical activity of a heart.

What is EKG?

If you need to check a patient’s heart rhythm, you’ll likely set up an EKG. Electrocardiograms are used to detect the electrical impulses sent out with each heartbeat. They provide information that can help you identify irregular heart activity and see if any parts of the heart are overworked.

What is EKG?

EKG is a common diagnostic tool in the medical field. Understanding how to perform an EKG is extremely valuable for any medical professional who works with cardiac patients. This course is also a prep course for ACLS and PALS to better understand rhythms.

How is EKG Done?

To conduct an EKG, electrodes are placed around the chest, arms, and legs. These electrodes are connected via wires to an EKG machine, which will measure the heart and print out a reading. Learn more about how to use an EKG in a training course.

I spent 15 years as a firefighter and paramedic, and reading an EKG does not have to be as hard as everyone makes it out to be…
When I was in medic school, I always wished I learned more about EKGs. They seemed intimidating and confusing at the same time and the last thing I wanted to do on the scene was misdiagnose a rhythm. Quick ECG interpretation can be the difference between life and death, so we set out to develop a series of EKG training courses that break it down for you in the simplest way possible – that way you’ll be confident when you need it most.

ECG and EKG are both acronyms for electrocardiogram.

You can refer to an electrocardiogram as an ECG or an EKG; the two acronyms are used interchangeably.

An EKG records the electrical activity of the heart. Its results can help you detect irregularities such as a fast heartbeat or an overworked part of the heart.

​​The three types of ECG include a resting ECG, an exercise (or “stress”) ECG, and an ambulatory ECG (also called a Holter Monitor).
