I ve been on blood pressure meds for a while due to lack of exercise during surgery. I have now been exercising again for 4 weeks & this past week my blood pressure has dropped (from 140 s/80 s to low 100 s/60 s) and my pulse rate has risen (from 60+ beats per minute to 90+ beats per minute). Also, I m experiencing shallow breathing. My doctor has had me stop blood pressure meds, but I haven t noticed a change. I had a heart ablation for Afib a couple of years ago 7 am wondering if it may have returned or if I m experiencing a different problem.
