Frequency and causes of QRS prolongation during exercise electrocardiogram testing in biventricular paced patients with heart failure.

I am a cardiac electrophysiologist specializing in the treatment of heart rhythm disorders and management of cardiac implantable electronic devices (CIEDs). My research utilizes signal processing of electrocardiographic data and novel analytic techniques to better phenotype patients and identify those for whom interventional electrophysiology procedures may be most beneficial. This includes predicting which patients with left bundle branch block may benefit from early cardiac resynchronization therapy or conduction system pacing. I also analyze population level data to identify patients at high risk for adverse sequelae of rhythm disorders who may benefit from early intervention.

Research interests include:
- optimization of device timing for Cardiac Resynchronzation Therapy (CRT)
- novel cardiac imaging technologies for CRT
- catheter ablation versus anti-arrhythmic drug for treatment of atrial fibrillation.

My research areas of interest include improving the safety and efficacy of complex ablation and optimal use of pacemakers in patients with heart failure, including cardiac resynchronization therapy and conduction system pacing. I am also interested in non-pharmacologic management of atrial fibrillation, including catheter ablation and left atrial appendage occlusion, and understanding optimal use of novel and emerging technologies.
