What does it mean when PVCs are described as "bigeminal"?

When PVCs, or premature ventricular contractions, are described as "bigeminal," it indicates that every second beat of the heart is a PVC. In this pattern, a normal heartbeat is followed by a PVC, then another normal heartbeat, and this sequence repeats. The term "bigeminal" stems from the Latin root "bi," meaning two, which fits this alternating pattern.

This distinction is important for healthcare professionals because the regularity and pattern of PVCs can influence treatment decisions and further evaluation. It allows clinicians to assess the potential impact of the PVCs on a patient's overall cardiac function and to determine if any medical intervention is necessary. Understanding this rhythm helps in monitoring patients experiencing arrhythmias and addressing any significant underlying issues.
