Mechanic is in the hospital

Hello, this is Trudy, his wife. He has been in the hospital since last Friday with heart problems. Mainly heart beating way too fast and then beating way too slow and flipflopping back and forth which could cause heartattack or stroke. He had a heart surgery last Tuesday that was unsuccessful in solving the problem. So now back to the drawing board to get a new game plan. Right at the moment they are trying to regulate it with medication but its not doing the whole job. I will try to keep you updated.
