Dr. Hugh Calkins is the Nicholas J. Fortuin M.D. Professor of Cardiology and Director of the Electrophysiology Laboratory and Arrhythmia Service at the Johns Hopkins Hospital. He is an internationally recognized expert on catheter ablation, atrial fibrillation, syncope, arrhythmogenic right ventricular dysplasia (ARVD) and arrhythmia management.

Dr. Calkins attended Williams College and Harvard Medical School before training in medicine at Massachusetts General Hospital. He received his cardiology training at Johns Hopkins. His first faculty position was at the University of Michigan, where he directed the Pacemaker Service, and he returned to Johns Hopkins as director of the Arrhythmia Service in 1992.

Dr. Calkins is an Associate Editor of the Journal of Cardiovascular Electrophysiology and is on the editorial board of many other cardiology journals. He is a former member of the American Board of Internal Medicine Electrophysiology Boards Test Writing Committee. Dr. Calkins is a fellow of the American College of Cardiology, the American Heart Association and the Heart Rhythm Society. He led a 44-member international task force whose 2012 Expert Consensus Statement gave recommendations for treatment and research of atrial fibrillation. Dr Calkins is a past president of the Heart Rhythm Society and was elected to be a member of the Miler Coulsen Academy of Clinical Excellence in 2014.

Dr. Calkins has published more than 500 articles and book chapters on a large variety of cardiac arrhythmias. His research has focused predominantly on catheter ablation, atrial fibrillation, syncope, and arrhythmogenic right ventricular dysplasia. Dr. Calkins has also written extensively on most aspects of heart rhythm disorders and their treatment.
