fast heartbeat long after done exercising

Why is it that it takes hours, sometimes 4-5 hours after done exercising for my heartbeat to go down?
Sometime it is still over 100 3-4 hours after I'm done.

Any help would be appreciated.

Have you ever mentioned the elevated HR to your doctor?

It may be normal for you, but because it is on the high end of "normal" it would probably be a good idea to have it checked out.

Have you just started working out recently?

This could be due to deconditioning, apparently. Talk to your doctor and take it down a notch.

When I was 21 years old I had really high blood pressure with palpitations for 2 years then one doctor told me I had alot of stress and I needed to exercise so one afternoon I played basketball for about 3 hours and that night when I went to sleep my heart rate would not go down at all so I finally fell asleep about 2 hours later, the next day I told myself I would not play basket again but that afternoon my friend kept telling me they needed one more person so I played again for about 3 more hours but the same thing happened at night, my heart rate wouln't go down, on the fourth day of playing hard for about 3 hours I noticed my heart rate was really normal and as soon as I hit the pillow I was asleep and for many years I felt great (of course I would be playing almost everyday).
