What would cause a pins in needle type rush feeling in head and fingers after having a skipped heart beat? no hyperventilation, no panic at the time.

There is more to it!: In susceptible persons, just a few altered breaths can change the acid-base balance of the blood like hyperventillation without the emotion of panic. A hidden risk here is that the "skipped heart beat" may be more than a single beat, ie a run of less than adequate heartbeats. There are several possible causes; please see your physician who can direct a painless workup in short order!
