Joshua Moss, MD
Associate Professor

500 Parnassus Avenue
San Francisco, CA 94117

Dr. Moss is interested in the evaluation and treatment of patients with complex heart rhythm disturbances. He has expertise in catheter ablation techniques for ventricular tachycardia and supraventricular arrhythmias, including atrial fibrillation and atrial flutter. He is also skilled in surgical implantation of pacemakers, defibrillators, and biventricular devices.

Dr. Moss both leads and participates in multiple clinical studies on existing and evolving techniques for treating patients with arrhythmias and congestive heart failure, including those with a ventricular assist device (VAD). Trained as an engineer prior to beginning his medical career, Dr. Moss also maintains an active research interest in novel device design for advanced cardiac rhythm management.
