My resting heart rate is in the high 60's. Did once get it down to 61 but as soon as I looked at the monitor- it went back up to 68. OK- I've had a bypass. When the Angina attack hit- The ambulance staff were worried that I had a heart rate as low as 45. and on went the sirens and get me to ITU as soon as possible- I stayed in that for 8 hours till the HR got back up to 60.
Heart rate will vary fronm person to person, and those of us with a higher heart rate will not have a problem as long as the pressure is within bounds and it is normal for you.
