electrophysiological study (EPS)

an invasive electrodiagnostic or manometric procedure that uses electrode catheters to pace the heart and potentially induce arrhythmias. The test identifies defects in the heart conduction system and arrhythmias that are otherwise inapparent. It also is used to assess the effectiveness of antiarrhythmic drugs.

Electrophysiological study

A test that monitors the electrical activity of the heart in order to diagnose arrhythmia. An electrophysiological study measures electrical signals through a cardiac catheter that is inserted into an artery in the leg and guided up into the atrium and ventricle of the heart.
