Joseph Marine, MD, MBA, FACC, FHRS, is a clinical cardiac electrophysiologist who practices primarily at the Johns Hopkins Hospital in Baltimore, Maryland. He is a Professor of Medicine at the Johns Hopkins University School of Medicine and holds appointments as Vice-Director of Operations for the Division of Cardiology and Section Chief of Cardiology for Johns Hopkins Community Physicians. He trained at UC San Francisco Medical School, Brigham and Women’s Hospital/Harvard Medical School, Boston University Medical Center, and Beth Israel Deaconess Medical Center.

Dr. Marine has lectured widely on a variety of arrhythmia topics and has served as a co-director of the American College of Cardiology (ACC) Cardiovascular Overview and Board Review Course for 10 years. He currently serves on the ACC Board of Governors and is co-editor of the ACC/HRS EP Self-Assessment Program. He also serves on other committees for the ACC, the Heart Rhythm Society, and MedChi. He is co-author of more than 130 original research and review articles and has served on writing committees for several national cardiology practice and training guidelines.

As a clinical cardiac electrophysiologist, Dr. Marine specializes in the diagnosis and treatment of arrhythmias, which are heart rhythm disorders that cause the heart to beat too rapidly, too slowly, or irregularly. His research focuses on further improving the safety and effectiveness of catheter ablation and other treatments for atrial fibrillation and other atrial and ventricular arrhythmias. more

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
