Dr. Andreas S. Barth is an assistant professor in the Division of Cardiology at the Johns Hopkins School of Medicine and Director of the Center for Inherited Heart Diseases. His clinical work focuses on clinical cardiac electrophysiology with a specific focus on inherited arrhythmia syndromes and channelopathies, including long QT syndrome, Brugada syndrome, CPVT and arrhythmogenic cardiomyopathies. Additionally, Dr. Barth participates in a multidisciplinary clinic at Kennedy Krieger Institute providing Cardiology care to patients with muscular dystrophies and mitochondrial disease. Dr. Barth performs pacemaker and defibrillator implantation and complex catheter ablations for atrial and ventricular arrhythmias.

His basic research lab explores the relationship between metabolic and arrhythmogenic ion channel remodeling in heart failure and myotonic dystrophy.

Dr. Barth earned a combined doctor of medicine and doctor of philosophy from the Ludwig-Maximilians-University in Munich, Germany. Dr. Barth is board certified in Internal Medicine, Cardiology and Clinical Cardiac Electrophysiology. He joined the Johns Hopkins faculty in 2016.

He has been recognized with the First Prize for the Stanley L. Blumenthal Cardiology Research Award in Clinical Science in the Division of Cardiology at Johns Hopkins Hospital, and as a Young Investigator Award Finalist of the American Heart Association and Heart Rhythm Society. 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.
