High Heart Rate and Faints Easily? Related?
I have fainted/passed out/ blacked out three times now, and its getting to be a problem I think, it always happens right after I work out. Usually when I go running, right when I stop running I will fall unconscious, or at least collapse. All three times, people have told me that my lips look white or brown, which I assume means that there is no blood flow to my head, because my vision also gets very dark before I faint. I get to the edge of fainting every few weeks where i can't stand up or see or talk, but i am not unconsious. I also notice that when I work out in the gym, my heart beat is very High. I will be walking on the treadmill on zero incline at about a level 3. my friend who is much heavier than me, walks at the same level on an incline, and her heart rate is about 120. my machine tells me my heart rate shouldn't go above 130, and yet it is about 150 when i am simply walking. on average my heart rate is about 95 just doing normal daily things like sitting in class. i am not overweight, i am 5'1 and 110 pounds. Slim in my opinion. but i am wondering why i faint after i excersise and if it has anything to do with my seemingly abnormally high heart rate
