Academic Interests

As an expert in cardiac electrophysiology, Andrew D. Beaser, MD, treats heart rhythm disorders. He is highly skilled in catheter ablation of cardiac arrhythmias, such as atrial fibrillation (AF), supraventricular tachycardia (SVT), and ventricular tachycardia (VT), utilizing both radiofrequency ablation and cryoballoon ablation (for atrial fibrillation). Dr. Beaser 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. In addition to his passion for patient care, Dr. Beaser performs research that mirrors his clinical interests. His work focuses 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. Dr. Beaser 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.
