About the Provider

Seth Worley, MD, joins the Section of Cardiac Electrophysiology as a senior consultant. An internationally recognized expert in cardiac resynchronization therapy (CRT), Dr. Worley brings with him extensive expertise in device and lead implantation for those patients who present with challenging vascular anatomy. He has personally developed unique tools and techniques to facilitate and optimize the success of transvenous left ventricular (LV) lead implantation. The approach he pioneered is referred to as ‘Interventional CRT” and patients from centers around the country who have had an unsuccessful attempt at lead implantation are regularly referred to Dr. Worley for treatment.

Dr. Worley joins MedStar Heart & Vascular Institute from Lancaster General Hospital in Lancaster, Pa., where he was the director of Interventional Implant Program at the Lancaster Heart and Vascular Institute. He is the founder and past president of the Lancaster Heart & Stroke Foundation, a non-profit organization dedicated to improving cardiovascular health through clinical research and community programs.

After completing a fellowship in cardiology and electrophysiology at Duke University Medical Center, he became the co-director of the Coronary Care Unit and Assistant Professor of Medicine. From Duke, he was recruited to the Mayo Clinic where he was Assistant Professor of Medicine in the Division of Cardiology prior to relocating to Lancaster. He is board certified in clinical cardiac electrophysiology, and a fellow of the Heart Rhythm Society.
