Same guy, my other instance seems to be down.

I'm not sure what you mean by a new heart rhythm. Once I got a healthy heart I've been at a normal sinus rhythm, rather than dealing with tachycardia and a bad arrhythmia, if that's what you mean. My rate is a bit elevated than a normal person's because the nerves that more closely control that get cut during the transplant (if my understanding is correct).

Otherwise, I did some physical therapy for a few months and have to take anti-rejection medication for the rest of my life, but I'm better than before by far.
