Get to know Cardiac Electrophysiologist Dr. David N. Pederson, who serves patients in San Antonio, Texas.

A renowned cardiac electrophysiologist, Dr. Pederson is affiliated with Methodist Cardiology Clinic of San Antonio. He is experienced in performing the cutting-edge Convergent Maze, or hybrid maze, procedure combining cardiac electrophysiology and minimally-invasive cardiac surgery to restore normal heart rhythms in patients with certain types of atrial fibrillation.

“Cardiac electrophysiology is a field where I can apply medical and surgical skills to diagnose and treat challenging, complicated conditions and watch my patients improve dramatically” expressed the doctor.

Methodist Cardiology Clinic of San Antonio is the largest cardiology practice in the San Antonio area, and has been providing superior, patient-centered services to patients since 1984. Throughout the metropolitan area, they provide a wide array of care in the prevention, diagnosis and treatment of cardiovascular diseases. In addition to the size and depth of expertise at their practice, their relationship with the Methodist Healthcare system allows them to provide best in class care for all cardiac and vascular needs.

Educated in the United States, Dr. Pederson obtained a Bachelor of Science degree in Biomedical Engineering from Loyola Marymount University, and received his medical degree from the Georgetown University School of Medicine. He completed both his internship and residency in internal medicine at Wilford Hall Medical Center at Lackland Air Force Base, achieving the rank of Lieutenant Colonel.

Subsequently, he completed his fellowship in cardiovascular disease at Letterman Army Medical Center at the Presidio of San Francisco in California, and his fellowship in clinical cardiac electrophysiology at University of California in San Francisco.

An authority in his field, the doctor is board-certified in clinical cardiac electrophysiology, cardiovascular disease and internal medicine by the American Board of Internal Medicine (ABIM). The ABIM is a physician-led, non-profit, independent evaluation organization driven by doctors who want to achieve higher standards for better care in a rapidly changing world.

Throughout his illustrious career, Dr. Pederson practiced on the staff of Wilford Hall from 1990 to 1996 while also serving terms as Director of Electrophysiology and Cardiac Pacing and Director of the Cardiology Fellowship Program. He then went on to serve as Assistant Professor of Medicine at the Uniformed Services University of the Health Services, as Clinical Instructor at University of Texas Health Science Center at San Antonio, and as Assistant Chairman of the Department of Cardiology at Wilford Hall. In 1996, he joined Austin Heart, a group cardiology practice, where he practiced as an electrophysiologist until joining Cardiology Clinic of San Antonio in 2002.

Clinical cardiac electrophysiology (also referred to as cardiac electrophysiology, arrhythmia services, or electrophysiology), is a branch of the medical specialty of cardiology and is concerned with the study and treatment of rhythm disorders of the heart. An electrophysiologist is a type of cardiologist. They focus on the heart’s timing, or electrical system, and on diagnosing and treating irregular heartbeats or arrhythmias. They are also qualified to perform special tests of the heart’s electrical system, such as an electrophysiology study or an ablation.

Among her most notable achievements, Dr. Pederson has been the recipient of the Top Doctor Award by San Antonio Magazine (2020), Patients' Choice Award (2015), Compassionate Doctor Recognition (2015), and On-Time Doctor Award (2014).
