Which of the following defines multifocal PVCs?

Multifocal PVCs, or premature ventricular contractions, are characterized by originating from multiple locations within the ventricles of the heart. This means that each PVC has a different electrical impulse that leads to a variation in its appearance on an ECG. This variability is a key feature that distinguishes multifocal PVCs from other types, such as unifocal PVCs, which arise from a single location and exhibit a consistent appearance. The presence of multifocal PVCs can indicate a more complex underlying cardiac issue, as they suggest multiple ectopic foci are triggering these premature contractions. Consequently, the identification of multifocal PVCs can be clinically significant when assessing a patient's cardiovascular health.
