I'm wondering if anyone can help me out.
I'm a 20 year old male in good physical condition and since I've been been about 12 I occasionaly experience a sudden rapid heart beat, normally during physical activity. My heartbeat will be normal for whatever activity I'm doing and then suddenly for no reason it will increase to what seems like 250 beats per minute and will literally be beating out of my chest. When this happens I sit down, breathe, and try to relax and whithin a few minutes it slows down to normal. During this time I become light headed, feel dizzy, and sometimes see stars. This has only happened when I'm playing a sport (basketball, frisbee, football) and never when I am running for exercize. And it has probably only happened to me about 20 times in roughly 8 years that I've experienced it. Can anyone tell me what it might be? |
