I was just lounging on the couch this morning and suddenly I felt nauseous, dizzy, and my heart was racing. It was going about 122bpm sitting down and 132bpm standing. My blood pressure was 98/76. All the doctors I've went to keep claiming this is just anxiety. The thing is, the only thing i'm worried about is my heart exploding in my chest! Not anything else! I'm not thinking about anything, and then it suddenly happens. Also, I would think if it were anxiety, then wouldn't my blood pressure increase, instead of lower? When I drink tons of water, my blood pressure increases and then it returns to a regular rythm. Like today, it was going about 122bpm sitting around. I drank about 16oz of water and my BP went to 128/76 with a pulse of 82. I also am getting this dizzy feeling while standing up, where I feel as if I'm getting pulled into the ground (like when in an elevator). Docs have never been able to get an accurate normal BP reading for me because I get TRULY anxious when in their offices. I'm wondering if somehow I have low blood pressure and that is what is giving me these symptoms?
