I have been experiencing the same thing. I had the holter monitor which showed hundreds of pvc's which are suppose to be harmless but are very unconfortable. The pcp gave me a beta blocker, propranolol, which I am hesitant to take given the side effects I have read about. I also have read about magnesium, particularly magnesium glycinate, as being helpful in some cases so I am going to try this. I am curious about which calcium/ mag/D formula one of the other respondents mentioned, Cara. If she sees this, please indicate.
