Think about it for a moment. You're in a sitting, lying down or bent over position.... You stand up and all of a sudden your heart needs to pump blood to areas that are low on it (mostly your head and it's called 'gravity'
). Thus the dizziness and of course your heart will beat faster to compensate. A palpitation or flutter is certainly not unusual under the circumstances.
I get this all the time, especially since I'm on BP meds for my heart disease. Eh.... it is what it is. Worst case, I sit down for a moment until things level out.
