Sorry for what will probably be a long post. For years I was on a blood pressure med--Lisinopril and a diuretic--which moderated my bp but had me peeing a dozen or more times a day. Embarrassing and inconvenient on long rides. A few months ago I was switched to a new med--Amlodipine-- which has me urinating more normally. BUT I've been feeling less strong, particularly on long, steep climbs. A nurse noticed the other day that my resting heartbeat, which used to be 55/62 bpm, was down to 43!

Could there be a connection between the lowered heart rate and decreased strength at max effort? My docs are so fixated on even mild hypertension as the root of all evil that I can't get straight answers from them about this kind of side effect.

BTW, I'm 75, 6'2", 200 lbs, and did 8000 miles last year, including six centuries.
