Do I have a serious heart problem I need to get checked?? PLEASE REPLY ASAP!!!? Well I honestly really dont know if this is a serious problem, but I find myself getting tired real easily. Even just by having a quick walk or getting excited for some reason my heart begins beating fast. It was never like this before and I never had any heart conditions, but now I can practically see it beating from my chest . I feel normal and everything is working fine, but is it normal to see your heart beat??? I REALLY need help on this, so if anyone knows why this is happening or if this is a serious issue I need to go get looked at please reply I d really appreciate it. Thanks.
