An electrophysiology (EP) study — also called invasive cardiac electrophysiology — is a series of tests that examine the heart’s electrical activity. The heart’s electrical system produces signals (impulses) that control the timing of the heartbeats. During an EP study, heart doctors (cardiologists) can create a very detailed map of how these signals move between each heartbeat.
An EP study can help determine the cause of irregular heart rhythms (arrhythmias). Sometimes it’s done to predict the risk of sudden cardiac death. An EP study is performed at Sapra Hospital by one of the best Interventional cardiologists with special training in heart rhythm disorders (electrophysiologists).
