EKG Certification Course

Upon successful completion of an EKG technician program, students can apply to take the nationally-recognized certification exam. These programs include hands-on training in a patient care setting. Many of these programs also require students to complete 40 hours of hands-on experience performing EKGs on a live person. This can be done in a cardiology doctor’s office, urgent care, or other healthcare facility.

During an EKG course, you will be taught how to take readings using an electrocardiogram (EKG) machine and how to interpret a rhythm strip. You will also learn how to disinfect equipment and understand the anatomy of the heart. You will have a chance to practice on a simulator, then move on to practicing on a live person when your instructor deems you ready.

EKG courses can be completed in as little as four weeks and are self-standing. You can also opt to attend an online program that is accredited by a national association. Some programs may also qualify for federal financial aid like MyCAA, GI Bill and other workforce funding options for veterans or active military spouses.

If you're preparing for multiple automotive certifications alongside your EKG studies, you may also find value in our 310t practice test, which covers truck and coach technician fundamentals.

Candidates balancing healthcare and trade credentials often supplement their EKG prep with our 313D practice test to strengthen their diagnostic reasoning across disciplines.

EKG Interpretation Certification

EKG or electrocardiogram is a test used to detect heart conditions. These tests are conducted by a technician who maintains a record and operates the equipment that records the electrical activity of the heart. They can also conduct heart tests like stress tests to analyze a patient’s health condition. These technicians are generally employed by physicians but can operate privately as well. They can be found in many healthcare settings including hospitals, clinics, and private offices.

Designed to provide an introduction to ECG and reinforce the interpretation skills of anyone who has some prior knowledge, it is particularly useful for division 1 registered nurses, ambulance officers and medical practitioners. It outlines the basic principles of the EKG waveform and provides a more specific review of infarctions; ischaemia and arrythmias.

This course is based on the book β€˜ECG Interpretation’ by Dr Araz Rawshani and offers an online e-textbook with video tutorials to help students learn ECGs. It is a case-based program that teaches/reinforces EKG interpretation skills through a proven educational method used by cardiology fellows for 15 years. The program presents unknown tracings for the user to diagnose and answers are promptly graded.
