In reading all these posts, I can relate to many. I wake up in the middle of the night feeling extremely warm, and when I take my blood pressure it's elevated very much and my heart beats fast. Has anyone taken their blood pressure when they get any palps? I am not on blood pressure medication as when I go to the dr my pressure is always normal, therefore no need for meds except for the wake up calls in the middle of the night which have not been so often, except for this week for some reason. A few years ago I took atenolol, a beta blocker and for me, it caused more stomach problems than I had without the pill besides severe anxiety. But everyone is different. I am so different. No one I know can understand what causes me to awake out of sleep with a racing heart, almost sweating and anxious. Lying awake I start worrying it's heart related, but I would think that if it were heart, then I would have some difficulty during the day too. I guess.
