Dr. Alexander G. Truesdell

Jonathan Chrispin, M.D., is an Associate Professor of Medicine in the Johns Hopkins Medicine Division of Cardiology, Electrophysiology and Arrhythmia, as well as an Associate Professor of Biomedical Engineering at Johns Hopkins University. Dr. Chrispin focuses on all aspects of clinical electrophysiology, including pacemaker/defibrillator implantation and complex catheter ablation for atrial and ventricular arrhythmias. Dr. Chrispin received his Bachelor of Arts degree from Harvard University. He received his Doctor of Medicine degree from Vanderbilt University. He completed intern and residency training in internal medicine at The Johns Hopkins Hospital, where he also completed a fellowship in cardiovascular disease and served as chief clinical cardiac electrophysiology fellow. He is a member of the American College of Cardiology, the American Heart Association, and the Heart Rhythm Society. Dr. Chrispin directs the Ventricular Arrhythmia Ablation and Research program, focusing on using advanced cardiac imaging to better understand the structural substrate associated with the development of ventricular arrhythmias and using artificial intelligence to improve the risk stratification of sudden cardiac death. Further, he is involved in developing clinical trials to improve the safety and efficacy of catheter ablation for the treatment of ventricular tachycardia. His work has led to Dr. Chrispin publishing in a number of international journals, including Circulation, the Journal of the American College of Cardiology, Heart Rhythm Journal, Nature Cardiovascular Research, Journal of the American Heart Association, and EP Europace. Dr. Chrispin is rated as an Elite provider by MediFind in the treatment of Ventricular Tachycardia. His top areas of expertise are Ventricular Tachycardia, Arrhythmias, Sarcoidosis, Cardiac Ablation, and Pacemaker Implantation.

Dr. Hugh Calkins is the Catherine Ellen Poindexter 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. Dr. Calkins is rated as an Elite provider by MediFind in the treatment of Ventricular Tachycardia. His top areas of expertise are Atrial Fibrillation, Arrhythmias, Cardiomyopathy, Cardiac Ablation, and Heart Transplant.
