Hi,
I had two stents around this time 2 years ago. Since then I have increased my exercise and walk typically 5 times a week, which I have built up to a pace of a KM in about 7 minutes doing just over 5K each of those days. Around 3 months ago my GP took me off my beta blockers, as my resting heart rate was dropping into the 30's. I was on the lowest dose as my resting heart rate is naturally low. As expected after coming off the beta blockers I saw my exercise heart rise but then it steadied at around averaging between 135 - 142.
In the last week I have seen the average rate jump up to 142 - 149 (the max is not much higher low 150's). Also my apple watch/iphone is reporting my VO2 Max has dropped. My resting heart rate average is also up around 4 bpm more than normal.
Should I be concerned or is it possible I have a virus or something similar? I have a few mornings this week woken up a little dizzy/light headed.
Thanks in advance!
