Can any one look at their chest and see it move to the beat of your heart? I also find that when I do some kind of physical activity, my heart beats fast. I think it's just that I think about it beating so it feels like it's beating more than normal. Does anyone feel like you heart beats fast when you run or exercise. I think I just think about it and that makes it worse? I've had numerous EKG's and blood tests,xrays, and so far their hasn't been a problem. Does exercise bring on a increase in your heart rate that feels more than normal. I hope this makes sense, even though it doesn't really??
