John is out of rhythm

John went to get his heart monitor put on this morning and they hooked him up to get a baseline. The nurse doing it said that this was the first time she had ever hooked someone up to one of these and got a reading as soon as she turned it on. He is definitely out of rhythm. She was worried about it, said there is something wrong they just have to figure out what. He goes in on Tuesday for the echo. Keep your fingers crossed.
