I have a question recently I have been experiencing fainting spells when I stand up basically my vision goes and I end up fainting it's really annoying I can feel my heart beating fast when these spells occur, my blood pressure is normal when sitting and standing. My doctor ran some tests and did a 24 hour heart monitor to rule out any cardiovascular problems however these are fine. I asked my doctor after reading online about postural orthostatic tachycardia syndrome (pots) and I will be undergoing a stand test. I did two at home just to see if it could be pots, do you guys think it is a possibility based on the results I took? Listed below thanks. Also I am 20 years old female with no other health conditions though I am always tired. Sorry if this is in the wrong section I did not know were to list this. Thanks again. Attempt one (Mid day) My resting heart rate was 95bpm after 3 mins of standing it rose to 126bpm, after 5 mins 151bpm and finally after 10 mins 135bpm. Attempt two (Morning) My resting heart rate was 113bpm after 3 mins of standing it rose to 155bpm, after 5 mins 159bpm and finally after 10 mins 153bpm.
