Dr. Day is à fàntastic Electrophysiologist. He performed a SVT AblatIon on me to stop my tachycardias two days ago, and I'm home now with no concerns, no pàin. He listened to my concerns about the procedure, and calmed any fears I had. I would highly recommend him to anyone who is having tachycardias.
