Possible Arrhythmia or Heart Attack?

I'm 19, 6'0 and 200 pounds. Despite my weight I'd say I'm not especially unhealthy, at least physically, not so much psychologically, for an American, and I've been getting more exercise recently so I'm starting to shed a few pounds. This morning I woke up with an abnormal heartbeat and slight chest pain. It could be stress but I'm worried it could be more serious. Should I see a doctor?
