Clinical cardiac electrophysiology is a branch of the medical specialty of cardiology and is concerned with the study and treatment of rhythm disorders of the heart. Cardiologists with expertise in this area are usually referred to as electrophysiologists. Electrophysiologists are trained in the mechanism, function, and performance of the electrical activities of the heart. Electrophysiologists work closely with other cardiologists and cardiac surgeons to assist or guide therapy for heart rhythm disturbances (arrhythmias). They are trained to perform interventional and surgical procedures to treat cardiac arrhythmia.<ref name="pmid35695795">{{cite journal | vauthors = Cox JL, Churyla A, Malaisrie SC, Kruse J, Kislitsina ON, McCarthy PM | title = A history of collaboration between electrophysiologists and arrhythmia surgeons | journal = J Cardiovasc Electrophysiol | volume = 33 | issue = 8 | pages = 1966–1977 | date = August 2022 | pmid = 35695795 | pmc = 9543838 | doi = 10.1111/jce.15598 }}</ref>

The training required to become an electrophysiologist is long and requires eight years after medical school (within the U.S.). Three years of internal medicine residency, three years of cardiology fellowship, and two years of clinical cardiac electrophysiology.<ref name="pmid30566044">{{cite journal | vauthors = DeMazumder D | title = The Path of an Early Career Physician and Scientist in Cardiac Electrophysiology | journal = Circ Res | volume = 123 | issue = 12 | pages = 1269–1271 | date = December 2018 | pmid = 30566044 | pmc = 6338224 | doi = 10.1161/CIRCRESAHA.118.314016 }}</ref>
