Advanced Concepts in Arrhythmias

by Nicholas G. Tullo, MD, FACC, FHRS


I wrote this article for the physicians training in cardiology who spent time with me on the electrophysiology service. It assumes at least a basic understanding of cardiac physiology and it can get rather technical, but is still written in fairly understandable terms. It discusses arrhythmia mechanisms to make it easier to make sense out of the myriad of rhythm disturbances we encounter in an electrophysiology practice. It is best to start at the Introduction and click "next" at the bottom of each page. If you only need information about a specific topic, click on one of the links below. If it gets too complicated, try reading the more basic article, Your Heart Rhythm. For those of you who would like to learn to read electrocardiograms, the best online ECG course available can be found at ECG Academy.
