Dr. Feld's primary clinical interest is in cardiac electrophysiology, and his clinical and research interests include the mechanisms of cardiac arrhythmias and catheter ablation techniques for atrial arrhythmias, particularly atrial fibrillation.

Dr. Feld is a Fellow of the American College of Cardiology, Member of the American Heart Association, Fellow of the Heart Rhythm Society, and is currently Associate Editor of the Journal of the American College of Cardiology.

Dr. Feld has been also selected as a Top Doctor in San Diego, and has been named one of the Best Doctors in America several times in recent years.

Research Interests:

Dr. Feld has been the primary author on numerous publications in the field of cardiac electrophysiology, with a particular emphasis on development of new antiarrhythmic drugs and methods of catheter ablation to cure cardiac arrhythmias. He has pioneered several new treatments for cardiac arrhythmias, including catheter ablation of atrial flutter and AV node modification for atrial fibrillation. His current research interests include optimizing techniques for catheter ablation of atrial fibrillation, and development of new energy sources for catheter ablation of atrial fibrillation, including cryoablation and microwave ablation.

Clinical Interests and Responsibilities:

Dr. Feld is currently Professor of Medicine at University of California, San Diego, and Director of the Cardiac Electrophysiology Program. His clinical responsibilities include performing up to 8 ablation procedures a week, as well as pacemaker and defibrillator implantation procedures. He also sees new and followup patients in his outpatient clinic one day a week. He currently performs the largest number of ablations for atrial fibrillation in southern California
