Wikipedia
Premature ventricular contraction
A premature ventricular contraction (PVC) is a common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node. PVCs may cause no symptoms or may be perceived as a "skipped beat" or felt as palpitations in the chest. PVCs do not usually pose any danger.The electrical events of the heart detected by the electrocardiogram (ECG) allow a PVC to be easily distinguished from a normal heart beat. However, very frequent PVCs can be symptomatic of an underlying heart condition (such as arrhythmogenic right ventricular cardiomyopathy). Furthermore, very frequent (over 20% of all heartbeats) PVCs are considered a risk factor for arrhythmia-induced cardiomyopathy, in which the heart muscle becomes less effective and symptoms of heart failure may develop. Ultrasound of the heart is therefore recommended in people with frequent PVCs. If PVCs are frequent or troublesome, medication (beta blockers or certain calcium channel blockers) may be used. Very frequent PVCs in people with dilated cardiomyopathy may be treated with radiofrequency ablation.

premature ventricular contraction
Premature ventricular contraction (PVC) is a type of abnormal heart rhythm, or arrhythmia, which occurs when the heart's ventricles contract too soon, causing a disruption in the normal heartbeat. This can occasionally cause the sensation of a "skipped beat" or palpitations. PVCs are usually harmless and do not necessarily indicate a serious heart condition, but in certain cases, frequent or long-lasting PVCs may indicate an increased risk of serious arrhythmias or heart diseases.

Premature ventricular contraction
A premature ventricular contraction, also known as a premature ventricular complex, ventricular premature contraction, ventricular premature beat, or ventricular extrasystole, is a relatively common event where the heartbeat is initiated by Purkinje fibres in the ventricles rather than by the sinoatrial node, the normal heartbeat initiator. The electrical events of the heart detected by the electrocardiogram allow a PVC to be easily distinguished from a normal heart beat. A PVC 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 and before the atria have optimally filled the ventricles with blood, which means that circulation is inefficient. However, single beat PVC arrhythmias do not usually pose a danger and can be asymptomatic in healthy individuals.
