Dr. Sinha is one of those rare doctors who can immediately put me at my ease. He has a lovely sense of humor and a way of minimizing any anxieties I may have with an extremely positive attitude. He performed my catheter ablation for A/fib 5 years ago and I felt very comfortable seeing him again for my atrial tachycardia. I left his office feeling very comforted and positive. Thank you Dr. Sinha!
