Research Interests

New Technologies for Catheter Ablation of Cardiac Arrhythmia; Applications of Advanced Imaging Modalities in Arrhythmia Management


Dr. Nazarian is a graduate of Stanford University School of Medicine, the Peter Bent Brigham Internal Medicine, and the Johns Hopkins University Cardiovascular Medicine and Clinical Cardiac Electrophysiology programs. For two years in a row he received the Richard S. Ross Clinician Scientist and the Johns Hopkins Clinical Research Scholars Awards. His clinical interests include the care of patients with atrial and ventricular arrhythmia, cardiomyopathy, and implantable cardiac devices. Dr. Nazarian performs procedures including implantation of permanent pacemakers and implantable cardioverter defibrillators, and catheter ablation for atrial and ventricular arrhythmias. He recently patented a noninvasive method for detecting the source of errant electrical signals that cause ventricular tachycardia.
