Personal Quote

I specialize in comprehensive arrhythmia management using the latest surgical and catheter based treatments. I perform advanced ablations to cure common arrhythmias such as atrial fibrillation and all supraventricular or ventricular arrhythmias. I implant and follow devices such as pacemakers and defibrillators, and use medications to suppress arrhythmia. Also, I use catheters to close the left atrial appendage for patients who are unable to take anticoagulation to prevent stroke.
