Or for that matter heavy exercisers who've experienced this! I'm just blown away by what has happened (and I think it is a GOOD thing!). May be long story.
I've always been a fairly vigorous exerciser, running or biking, and engaging in heavy work (but was a desk jockey for the most part in my career). Even checked the marathon box, Grandfather Mountain M, did in little over 4 hours. Have no long term issues other than a slight heart murmur that has been baseline monitored with echocardiogram, pretty much dismissed as nothing to worry about.
Am currently 65 and over last few years BP has been creeping up, at annual physical GP said to get a monitor, watch it, and if it was consistently where he measured (143/90) to fill a scrip he gave me for metoprolol, a beta blocker. Started it three days ago and noticed almost immediate reduction, down to 130 over 90 or less, and resting HR dropped from high to low 70's (my HR always has been high). So cool, doing what it should, and I had noticed on web before I got it that it could lower HR.
I've used Garmin HR monitor running and biking and Expresso bike at Y that is pretty rigorous recording HR and wattage. I consistently get HR to mid 160's, average maybe 150 or so over 50 minutes of pretty rigorous activity. At Y the bike says 150 watts is usually my average, so you can pretty much gauge output vs HR.
Today was the first day I've been to gym since started the metoprolol, didn't expect anything out of ordinary or to even look for any changes. Got near end of 50 minutes of not a super vigorous, but pretty hard ride averaging 140 watts. Looked at monitor and said HR was 110. I assumed that could NOT be right, machine must be off. As soon as got done did a manual check of pulse, and it was spot on. Checked web record of my rides and for similar average wattage I usually average HR of 140 or so. Today it was 105.
I asked the nurse there about it and she said yes, beta b will reduce HR but she was not aware of such a reduction while under heavy exercise. I had NO feeling of being stressed or in any way different from prior rides like this. How can my heart possibly sustain my body under identical exercise yet beat 25% less? Engineer here, this is a positive displacement pump so what is going on? Lower BP less back pressure? Somehow more efficient? I've never had a cardiologist but this makes me want one just to answer these questions! I've looked around web but don't see anything relative to the drugs and HR under exercise but I'm sure it's out there. I can only assume this phenomena is a good thing, I'm just incredibly astonished at how a drug can have this effect.
Anyway, anyone have any knowledge of this or experience directly with it? Thanks!
