I am a clinical cardiac electrophysiologist, and I study the comparative effectiveness, cost-effectiveness and clinical outcomes associated with cardiac arrhythmias and their treatments. , cardiac electrophysiology and exercise physiology. I have an NIH funded career development award (K23) to study the comparative effectiveness of ablation for atrial fibrillation compared with medical therapy for the prevention of long term adverse outcomes such as death and ischemic stroke. I am also conducting research sponsored by the American Heart Association and industry focused on ICD therapy, heart failure, and atrial fibrillation.
Specialized Terms: Arrhythmias; atrial fibrillation; atrial flutter; ventricular tachycardia; ventricular fibrillation; implantable cardioverter-defibrillator; cardiac ablation; outcomes research; cost-effectiveness
