Electrophysiology

What is an Electrophysiology?

The study of the heart’s electrical system is what is referred to as electrophysiology. The heart's electrical system controls the rate and rhythm of the heartbeat. Any procedure that requires an electrode catheter to be inserted into the heart is called an electrophysiology study (or EP study). Electrode catheters are long, thin, flexible wires that send electrical currents through the heart.
