Have any of you been on Coumadin or other blood thinners, and noticed any effects on your heart rate range? I am taking this drug because I had a catheter ablation done on my heart for Afib about 6 weeks ago.
Now I'm finding that my resting heart rate is about 90, and the max I have been able to get it to is ~160 (although I need to check this again today). Before the surgery, I always had a high resting rate of somewhere in the 70-80 range even when I was very fit (ran low 14's for 5k, etc...). However, my max HR was at least in the high 180s if not 190s.
I'm fit now, and have no problem working out at low to medium intensity levels, but can't tell how much this is holding me back when I try to go hard. Also, no lectures necessary on not worrying about this and just staying healthy. I don't really care if I can't compete at a high level anymore. I only want to know if this heart rate limitation is somehow related to the coumadin, or maybe the surgery.
any input would be appreciated.
