No, Steve, doctors actually do stop a patient's heart to reset a super fast heart rate. I learned this first hand when I suffered from atrial fibrillation recently and my pulse climbed to 320 beats per minute. Thankfully, they do this while you're asleep and it wasn't necessary in my case. I believe supraventricular fibrillation is even more serious than atrial fibrillation.
Starflier, that is the best plan I've heard in a long time. I hope you find the life you're looking for. It's there for the taking.
