What defines ventricular bigeminy?

• A. Every fourth beat is a PVC
• B. Every other beat is a PVC
• C. Three PVCs in a row
• D. Regular heartbeat with missed beats

Answer: (B)

Ventricular bigeminy is characterized by a pattern where every other heartbeat is a premature ventricular contraction (PVC). In this arrhythmia, the normal sinus beat is followed by a PVC, creating a distinct alternating rhythm. This results in the heart essentially having two types of beats: a normal beat followed by a PVC, making it easy to identify when monitoring telemetry. This concept reflects the rhythmic nature of bigeminy, where the presence of PVCs interrupts the usual regularity of heartbeats. Recognizing this pattern is crucial for telemetry monitor technicians, as it helps in assessing the patient's cardiac status and the need for further intervention. Understanding how bigeminy presents itself can aid in distinguishing it from other arrhythmias, which might not exhibit the same alternating pattern.
