"Skipped Heartbeats." Premature contractions — PACs and PVCs. PVCs, not to be confused with polyvinyl chloride plastic tubing of the same name, are extra heart beats which can feel scary, but in fact, are an important safety mechanism for the heart. Premature ventricular contractions, or PVCs, are a type of abnormal heartbeat. Premature ventricular contractions can be associated with: The following can increase your risk of PVCs: Having frequent PVCs or certain patterns of them might increase your risk of developing heart rhythm problems (arrhythmias) or weakening of the heart muscle (cardiomyopathy). PVCs that occur frequently or for longer periods of time are more likely to be related to heart disease, an injury to the heart or other, non-cardiac conditions such as a chemical imbalance in the body.
