I usually have normal sinus rhythm, but during the past two weeks i have been awoken with heart skipping beat and the next beat a hard heart beat. this has happened twice now. i dont feel bad, but concerned.

Premature beats: You're experiencing premature beats or extrasystoles. The forceful beat is the next normal beat after the pause that follows the premature beat. You would have to wear an outpatient holter monitor to determine whether the premature beats are atrial, ventricular or av nodal. It would also tell you how many premature beats occur in 24 hours, ?runs& when they are most prevalent, Discuss with your MD
