Cardiac electrophysiology is the science of elucidating, diagnosing, and treating the electrical activities of the heart. The term is usually used in a clinical context to describe studies of such phenomena by invasive (intracardiac) catheter recording of spontaneous activity as well as of cardiac responses to programmed electrical stimulation (PES), see Clinical cardiac electrophysiology. Cardiac electrophysiology also encompasses basic research and translational research components. Someone who studies cardiac electrophysiology, either clinically or solely through research, is known as a cardiac electrophysiologist.
