What does PVC stand for in cardiac monitoring?

Premature Ventricular Contraction is a term used to describe a specific type of heartbeat that occurs when the ventricles contract earlier than they should in the cardiac cycle. This early contraction interrupts the normal rhythm of the heart, which can lead to a sensation of a skipped heartbeat or palpitations in some individuals. PVCs can occur sporadically, and while they can be benign in healthy individuals, a higher frequency can be indicative of underlying cardiac issues that require further evaluation.

Understanding PVCs is crucial in cardiac monitoring because they can be a sign of electrolyte imbalances, structural heart changes, or ischemic heart disease. Continuous monitoring is often employed in clinical settings, particularly in patients at risk of arrhythmias, to assess the frequency and pattern of these contractions, helping healthcare providers determine if any intervention is needed.

The other options presented do not accurately reflect the commonly accepted terminology used in cardiology to denote this specific phenomenon.
