Essentials of electrocardiography is designed to help you understand the fundamental knowledge and skills necessary to successfully perform an ECG. Its concise yet comprehensive coverage includes instruction on the anatomy of the heart, electrophysiology of the heart, and ECG basics. To prepare you for completing ECGs in the field, a combination of introductory cardiovascular anatomy, relationships of other body systems to heart health, need-to-know legal and ethical considerations, patient assessment techniques, instructions on how to complete and document ECGs, and basic interpretation of the ECG tracing are included.

What is the difference between EKG and ECG? There is no difference between an ECG and an EKG. Both refer to the same procedure, however one is in English (electrocardiogram – ECG) and the other is based on the German spelling (elektrokardiogramm – EKG).

This program is recognized by NHA.
