Christie A. Crean is on staff in the electrophysiology lab in the cardiology department at Morton Plant Hospital in Clearwater, Fla., and at The Heart and Vascular Institute of Florida in St. Petersburg.

DURING AN electrophysiology study (EPS), electrode catheters are percutaneously placed in precise areas of the heart to record and stimulate electrical impulses. These catheters help pinpoint the location where impulses originate and monitor how fast they occur. The electrophysiologist may send electrical stimulation through the catheters to the heart muscle to induce or reproduce dysrhythmias in the controlled environment.

The electrophysiologist can use EPS findings to diagnose many different cardiac conduction problems, including accessory pathways, reentry circuits, activation sites of abnormal cardiac impulses, and the status of the normal conduction pathway. The findings help determine if the patient will benefit ...
