question: I awake in the morning with what I presume are palpitations, where it feels like my heart is beating very hard-not sure that it is racing however. I sleep quite well and don't perceive myself to be stressed. My blood pressure and heart rate after moderate exercise are normal. More often I have been told my BP is on the low side.I am a healthy active 60 year old female, but of course concerned as my maternal grandparents were felled by stroke.I wondered if this may have to do with menopause
