He spent the next several years in cardiovascular and cardiac electrophysiology training, under the tutelage of Dr. Mark Josephson at the Hospital of the University of Pennsylvania. This experience helped him gain recognition as an expert in catheter and intraoperative mapping and ablation of ventricular tachyarrrhythmias.
Areas of special interest include complex catheter ablation procedures for supraventricular and ventricular tachyarrhythmias (including atrial fibrillation) and innovative diagnostic methods for distinguishing among different arrhythmias.
Research: Mechanisms of arrhythmias; ablation of complex arrhythmias; atrial fibrillation; ventricular tachycardia; pacemakers and implantable defibrillators
Clinical Interests: Diagnosis and treatment of complex cardiac arrhythmias; catheter mapping and ablation technologies; implantable device therapy
Several lines of investigation are focused on trying to understand some unusual phenomena observed during catheter ablation of atrial fibrillation and flutters. Other studies are evaluating different techniques of improving outcomes during complex catheter ablation procedures for treatment of atrial arrhythmias in different patient populations, including those with repaired congenital heart disease. Several studies are evaluating techniques for determining optimal catheter ablation approaches in patients with symptomatic premature ventricular complexes and ventricular tachycardia.
