What describes Bigeminy in relation to PVCs?

Bigeminy refers to a specific pattern of premature ventricular contractions (PVCs) in which every other heartbeat is a PVC. This means that for every normal heartbeat, the subsequent heartbeat is a PVC, creating an alternating rhythm. This can often be observed in an electrocardiogram (ECG) and is characterized by a regular sequence: normal heartbeat, PVC, normal heartbeat, PVC, and so forth.

Understanding the significance of this pattern is vital, as it can indicate underlying cardiac issues, and may require monitoring or intervention depending on the overall context of the patient's cardiac health. The other options describe patterns of PVCs but do not align with the definition of bigeminy, making it clear that every other beat being a PVC is the defining characteristic of this arrhythmia.
