Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of the heart's two lower pumping chambers (ventricles). These extra beats disrupt the regular heart rhythm, sometimes causing a sensation of a fluttering or a skipped beat in the chest.
Premature ventricular contractions are a common type of irregular heartbeat (arrhythmia). PVCs are also called:

Premature ventricular contractions often cause few or no symptoms. But the extra beats can cause unusual sensations in the chest, such as:
To understand the cause of premature ventricular contractions (PVCs), it might help to learn more about how the heart typically beats. The heart is made of four chambers — two upper chambers (atria) and two lower chambers (ventricles). The heart's rhythm is controlled by a natural pacemaker (the sinus node) in the right upper chamber (atrium). The sinus node sends electrical signals that typically start each heartbeat. These electrical signals move across the atria, causing the heart muscles to squeeze (contract) and ...
Most people with premature ventricular contractions (PVCs) who don't have heart disease won't need treatment. If you have heart disease, PVCs can lead to more-serious heart rhythm problems (arrhythmias). Treatment depends on the underlying cause.
A health care provider may recommend the following treatment for frequent PVCs:
