you might have exercise induced SVT. supraventricular tachycardia. it can often be exercise induced. hard to pick up on an ekg since its random, you can talk to your doc about getting a holter monitor to wear for a week. i would at the very least see your primary about an EKG to start off with

its not really that serious. you can try doing a valsalva maneuver next time it happens to see if it fixes it.

but it could be something else. i'm a doc but this is a forum and i don't know your medical history.
