About me

Cardiac Electrophysiologist Glenn Meininger, MD, is the Director of Cardiac Electrophysiology Services for the Baltimore region of the MedStar Heart & Vascular Institute. He is board certified in cardiac electrophysiology, cardiovascular disease, and internal medicine.

Dr. Meininger specializes in treating patients with heart rhythm disorders, or arrhythmia, and helps people manage arrhythmia using a variety of techniques, including catheter ablation, electrophysiology testing, pacemakers, defibrillators, medication, and lifestyle changes. Because heart-rhythm disorders often involve a number of contributing health factors, he takes the time to understand the cause of the problem, so he can recommend a treatment plan that addresses all health concerns a plan that improves his patients' quality of life.

With a degree in mechanical engineering from the University of Pennsylvania, Dr. Meininger believes there's a natural overlap between engineering and the structure of the heart, which he sees as a sophisticated pump with an electrical regulator. He chose a career in medicine because it allowed him to focus on people, and he values the ability to make a positive difference in his patients' lives.

Dr. Meininger grew up in Columbia, Maryland and trained at the Johns Hopkins University School of Medicine, completing his cardiology and cardiac electrophysiology fellowship. He has taught medical students and residents in electrocardiography. He participates in numerous studies in arrhythmia management and treatment and has contributed to more than 30 articles in leading medical journals and is a fellow of the American College of Cardiology and the Heart Rhythm Society.

A former collegiate soccer player at the University of Pennsylvania, Dr. Meininger enjoys participating in triathlons and watching his five children play sports.
