Electrophysiology & Arrhythmia Services

The UCSF Cardiac Electrophysiology and Arrhythmia Service is known worldwide for the evaluation and treatment of patients with a variety of cardiac arrhythmias, or abnormal heart rhythms. Electrophysiology, a subspecialty of cardiology, is a rapidly growing field on the forefront of discovering cures and new treatments for all forms of arrhythmias.

Over the past two decades, tremendous advances have been made in understanding the mechanisms of cardiac arrhythmias. The Electrophysiology Service has a history of innovation and is a leader in advancing the assessment of the heart's electrical functions. In the 1980s, doctors at UCSF Medical Center pioneered the use of catheter ablation, a treatment that destroys or disrupts parts of the electrical pathways causing arrhythmias. Today, we use this technique to successfully treat a variety of cardiac arrhythmias.

Our team of experienced electrophysiologists, nurses and technicians is devoted to the care of patients with abnormal heartbeats. We perform over 900 procedures a year, including 400 catheter ablation procedures. This high volume ensures efficiency and expertise in the treatment of arrhythmias.

Cardiac Electrophysiology and Arrhythmia Service maintains a vigorous research program. The service develops and participates in clinical trials, research studies involving experimental therapies, with the National Institutes of Health (NIH) and the Food and Drug Administration (FDA) as well as pharmaceutical and device companies to discover better treatments. These trials give patients access to many new investigative therapies, devices and medications that may be more effective than traditional treatment methods. In turn, this research and the development of new technologies and treatments allow the Electrophysiology Service to provide specialized and personalized care for our patients.
