Arrhythmias Tutorial

Reviews cardiac electrophysiology and discusses how to approach arrhythmia diagnosis. This title teaches the genesis and propagation of the heart's electrical activities and how surface ECG reflects these activities. It covers sinus node function and dysfunction, APCs, and the major supraventricular tachycardias.

This tutorial covers sinus node function and dysfunction, APCs and all of the major supraventricular tachycardias: atrial fibrilation and flutter, multifocal atrial tachycardia and PSVT (paroxysmal supraventricular tachycardia). The Wolff-Parkinson-White syndrome and its associated arrhythmias are discussed as is the use of digitalis, adenosine, beta blockers and calcium channel blockers to treat supraventricular tachycardias. There is also a discussion of the carotid sinus reflex and its clinical significance and the appropriate use of carotid sinus pressure in arrhythmia management.
