Andrew D. Beaser

Assistant Professor
Department of Medicine

As an expert in cardiac electrophysiology, Andrew D. Beaser treats heart rhythm disorders. He is highly skilled in catheter ablation of cardiac arrhythmias such as atrial fibrillation, supraventricular tachycardia, and ventricular tachycardia, utilizing both radiofrequency ablation and cryoballoon ablation (for atrial fibrillation). He specializes in pacemaker and defibrillator implantation procedures, including both transvenous and subcutaneous ICD systems, as well as laser lead extraction procedures through his focus on lead management. His research mirrors his clinical interests, focusing on lead management through ensuring safer and more successful lead extraction procedures, and finding novel uses for radiofrequency ablation techniques for non-arrhythmic cardiac disease. He is interested in risk factors for sudden cardiac death through understanding the mechanisms underlying arrhythmia. He is also committed to education, always striving to teach trainees about cardiac electrophysiology.

Beaser received his MD from the University of Massachusetts Medical School and completed his residency in internal medicine at Tufts Medical Center, where he served as chief resident. He also completed fellowships in cardiology and cardiac electrophysiology at the University of Chicago.
