I have repair ToF and two subsequent surgeries. My most recent surgery was September 25th of last year. I am a casual runner - I like to run 2 miles 3-4 times a week. At 3 months post-surgery, I ran/walked 2 miles a day for 5 out of seven days. Felt good and no issues.
Now I am 5 months post-surgery and I am running more and walking less on my 2.25 mile treks. I always check my pulse post-exercise. I typically take a 5 minute cool down after running, btw. The last two times I ran, my post-exercise PR = 58 bpm. It takes about 3-4 hours for my PR to return to the 80s - where is has been for the last two months. No symptoms related to the low bpm with the exception of feeling like I have a "heavy" heart beat.
I have had multiple ablations for atrial fib and flutter, and this "heavy" heart beat doesn't feel like flutter to me. I am a little gun shy about running more. I want to run a 5k in two weeks, but don't know if I should. I will be asking my cardiologist in a few days, and I wanted to see if I get any other thoughts from this site.
