Elevated heart rate after exercise

[ICU812]

This has probably done to death and probably has some scientific explanation I hope
I did a particularly hard RPM class today. I have noticed that my HR has remained elevated for quite some hours.
My HR monitor is getting a new battery so I can only estimate it is around 90 - 100bpm
Does this always happen after hard exercise? I'm hoping it doesn't hurt you in any way?
Many thanks Sam

It shouldn't happen for that long. If you do a lot of strenuous exercise your heart rate will go up, but when you finish the exercise and rest, it should come back down within 5-10minutes.
Elevated heart rate for several hours after exercise should be checked by your doctor.

having said that, check your heart rate monitor, it might be dodgy and a flat battery can contribute to it. Also you might naturally have a high resting heart rate.

You best bet is to see your doctor and have then check your ticker just in case
