Cardiac Electrophysiology, Clinical

• Clinical cardiac electrophysiology is a subspecialty of cardiology dealing with the evaluation and management of patients with complex rhythm or conduction abnormalities. The clinical electrophysiologist uses complex catheter mapping techniques to determine the precise mechanism of various rhythm abnormalities and to help guide appropriate therapy. Modern treatment options may include electronic devices such as implantable cardioverter-defibrillators or advanced pacing systems. Radio frequency catheter ablation techniques have recently revolutionized the treatment of certain specific rhythm disturbances. Clinical cardiac electrophysiology is a very important adjunct to a modern complete cardiology program.
