What is premature ventricular complex?

A premature ventricular complex (PVC) is an early heartbeat originating from the ventricles of the heart, resulting in an irregular heartbeat. PVCs occur when the ventricles contract prematurely, disrupting the normal heart rhythm. While they are often benign and can be experienced by healthy individuals, frequent PVCs may indicate underlying heart issues and should be evaluated by a healthcare professional. Symptoms can include palpitations, but many people may not experience any noticeable signs.
