I'm 62 years old and my first case of A-Fib started in 1995. Since then I had 9 cardio-versions, the last one was done on November 2010. I was sick and tired of taking medications, going back into A-Fib and having to take warfarin. So, I had an Ablation done on January 4, 2011. It went well and I'm off Flecaninde but he still has me on warfarin. I hope he takes me off the warfarin this week, I will be pushing for this. I'm having a low heart readings at rest (45-55 average rates per min) and my blood pressure is (140/89 average) when I first wake up in the morning. When I exercise rigorously for 1 hour I start to feel better and my heart rate increases. I usually bring my heart rate up as high as 130 during exercising. At rest, after about an hour after exercising, my heart rate is (60-70) and my blood pressure runs on the average of (112/73). At times I feel a little light headed and weak but when I go out and shovel the driveway or exercise on my bike or treadmill these systems go away and I feel great. Would warfarin cause me to have a low heart rate at rest and light headness?

Would the low heart rate be because of my extreme exercising for many years that made my heart stronger and need not to be beating at a higher rate at rest? My wife says I'm over doing it (exercising) but I've been doing this all of my life. I always worked hard and I played many sports since my youth and jogged many miles until my Bi-TKR (2003 & 2004) but I still walk 4 miles a day in one hour every day or I'm on the stationary bike doing 12 miles in one hour on a 10 percent grade setting.

My doctor had mentioned that I had a low heart beat a few weeks ago and said I will need to wear a monitor for a day. He mentioned a pacemaker but I'm not cool about this! Is my doctor over reacting for me needing a pacemaker? My heart beats perfectly when exercising and my blood pressure is great after exercising. Could you please give me some advice seeing what I have told you. Thank You!
