Rapid heart when slight exertion

[Luceecain]

Does anyone else have this problem? When I do the slightest activity (especially in the morning) my heart rate will race to about 170bpm. I have had many heart tests which show a normal heart. However I want to know why it does this to me?

How is your blood pressure when your heart rate increases? If your pulse elevates when you get up in the morning you might have “orthostatic hypotension.” Your blood pressure would drop after you went from lying to standing. Your heart would then start working harder.

Could you be dehydrated? Does this follow tea or coffee that would result in more lost fluid?

My blood pressure is always quite low but not extremely low. I drink water constantly and I never drink caffeine
