Background
Dr. Aronis is an Assistant Professor of Medicine in the Division of Cardiology at the Johns Hopkins School of Medicine, the Director of the Complex Adult Congenital Heart Disease Ablation Program, and the Associate Director of the Ventricular Tachycardia Ablation Program. He performs all types of electrophysiology procedures, with a special focus on complex catheter ablations for atrial and ventricular arrhythmias as well as complex ablations for arrhythmias in patients with adult congenital heart diseases.
Dr. Aronis received his M.D. and Ph.D. degrees with Summa Cum Laude honors from the University of Patras School of Medicine in Greece. He completed his internal medicine residency training at Boston University Medical Center both his Cardiovascular Disease and Clinical Cardiac Electrophysiology fellowships at The Johns Hopkins Hospital. In addition, he has completed a post-doctoral research fellowship in Translational Research at Beth Israel Deaconess Medical Center / Harvard Medical School and an NIH funded (T-32) post-doctoral research fellowship in computational electrophysiology at the Institute of Computational Medicine at the Johns Hopkins Whiting School of Engineering. He actively engages in clinical trials and research studies aimed at improving patient outcomes and advancing the understanding of cardiac arrhythmias. He is a member of the American College of Cardiology, American Heart Association, and Heart Rhythm Society.

The doctor and his team gave back to me my stamina, energy and basically a much better life. And I just thought that was a general decline due to my age. ( never been 67 before). I feel as if have been re-born again. What Dr. Aronis gave to me with the procedure he performed I would not believed it. But I am living it and getting stronger every day. Thank you Dr. Aronis and [staff] for his recommendation. I have been seeing [staff] for quite sometime and think the world of him.
