Clinical Interests

My clinical interest spans all of cardiac electrophysiology, dealing with slow and fast heart rhythm problems.  My clinical expertise includes all cardiac device implantations related to heart rhythm disturbances, as well as a comprehensive list of cardiac ablations (cauterization) to improve or cure arrhythmias occurring in both the top and bottom parts of the heart (including atrial fibrillation and ventricular tachycardias).

Patient Ratings

The Patient Rating score is an average of all responses to care provider related questions on our independent rating system, the Press Ganey Patient Satisfaction Survey. This survey is about the patient care experience and does not address crucial characteristics like medical decision-making, prescribing the best therapy, and patient outcomes.

Responses are measured on a scale of 1 to 5, with 5 being the best score. Learn more about our patient satisfaction survey.
