A premature ventricular contraction occurs when a focus in the ventricle generates an action potential before the next scheduled sinoatrial nodal action potential.

Unlike premature ventricular contractions, or PVCs, which are wide-complexed because they do not use the normal ventricular conduction system.

Premature Ventricular Contraction Diagnosis Even if you've never had symptoms, you may be diagnosed with PVCs during a routine heart test called an electrocardiogram (ECG).

If you feel like your heart occasionally skips a beat, you could actually be having an extra heartbeat. One condition that causes this extra beat is premature atrial contractions.
