Overview
Premature ventricular contractions can be classified based upon the number of normal beats between them.
Classification
- There are four different named patterns of regularly occurring PVCs.
- Depending whether there are 1, 2, or 3 normal beats between each PVC, the rhythm is called bigeminy, trigeminy, or quadrigeminy.
- Unifocal PVCs are triggered from a single site in the ventricle, causing the peaks on the ECG to look the same.
- Multifocal PVCs arise when more than one site in the ventricles initiate depolarization, causing each peak on the ECG to have a different shape. If 3 or more PVCs occur in a row it may be called ventricular tachycardia.[1]
