During my cardio workouts it gets up to 185 and lowers to 90 in 2 minutes. I feel the slow heart rate and sometimes get dizzy. I have to see a cardiologist annually to ensure it’s ok as I age - female 50 yrs. Slow heart isn’t always good.

This. My otherwise fit father's RHR is so low that when he was 75 and his cardiologist put him on a monitor for a few days of testing, my mom got a call in the middle of the night to wake him, and they canceled the rest of the test and immediately scheduled him for a pacemaker.

I also have a low RHR. I'm 60 y.o
and active (lots of walking, lift weights 2x/week) but not an athlete. RHR averages 54. It's much lower now than it was 10 years ago, so I assume that I too am headed for a pacemaker at some point.

Age 55, F
Overnight HR is 47-49 and top HR is 120, doing high intensity Peloton. Always had low BP - 110/64. These are genetic, Mom has similar stats. I've never been a real athlete, but I'm a very consistent exerciser and have been lifting heavy for the last 4 years, plus Peloton/walking 3/5x weekly.

+1 My heart rate is naturally high, never below 70 and often in the 90s. I’m 5’3” and petite, was 110 pounds until recently. BP is normal,
