Premature Ventricular Contraction 

when your heart skips a beat.

may be perceived as a "skipped beat" or felt as palpitations in the chest. In a normal heartbeat, the ventricles contract after the atria have helped to fill them by contracting; in this way the ventricles can pump a maximized amount of blood both to the lungs and to the rest of the body . In a PVC, the ventricles contract first, which means that circulation is inefficient. However, single beat PVC arrhythmias do not usually pose a danger and can be asymptomatic in healthy individuals.1

Babe, you make me have premature ventricular contractions. <3
