This course consists of video tutorials that will teach you how to read an electrocardiogram.  It starts with a Pretest that will demonstrate your knowledge of ECGs before starting.  Level 1 starts with electrical theory, cardiac anatomy and physiology, lead placement, interval measurements, and then teaches rhythm strip and arrhythmia analysis. Level 2 then goes on to cover topics needed to read a 12-lead ECG. 

An essential part of the course are the ChalkTalks, which are 5-6 minute "how to" videos that show you on the screen how to approach an unknown tracing. There are ChalkTalks included in the course, plus a new ChalkTalk is released every week. Your subscription will last 1 year, so you can use this as a valuable resource even after you finished the course.
