Pre-Op EKG wasn't normal; slow heart beat, under 50 resting

I had my pre-op yesterday at the hospital for my Nov 15th surgery. The EKG showed my heartbeat was under 50. On my previous EKG in May it was over 50, though I've always had a slow heart beat. The surgeon's office called and told me I had to have a clearance from a Cardiologist before the surgery. As far as I know I don't have any heart issues, but I'm pretty nervous now. I'm 42, weigh 268 and have a family hist ory of heart disease (dad had a bypass at 42, grandmother died of heart attack at 67). I think (or hope) the slower heart rate is because of the exercise. Any comments? My appt with the Cardiologist is tomorrow. Thanks, Christina

I cant give any advice, but i do wanna send tons of postive vibes your way~~~~

I thought I would post an update, in case someone else comes across this same issue. I had a stress Echo today and it turned out normal. I guess I just have a slower heartrate and that's OK. So my surgery hasn't been cancelled. Christina
