Vaccinated in March with Moderna and got a mild case of delta a month ago. I now can not get my heart rate above 140 no matter how hard I try. Power is down a bit as well but I think that’s a function off time off bike.
Prior to either of those I could easily crack 200+ BPM in a hard effort. Anyone else seeing anything similar? Primary care doc didn’t take it at all seriously and said not worry about it.
