In PVC context, a Couplet is

• A. Two consecutive PVCs
• B. Three consecutive PVCs
• C. Four consecutive PVCs
• D. A single PVC

Answer: (A)

In this context, a couplet means two premature ventricular contractions that occur back-to-back with no normal heartbeat between them. A single PVC isn’t a couplet, and having three or four consecutive PVCs would be described as triplets or a longer run, not a couplet. Recognizing two consecutive ectopic beats is important because it indicates a higher burden of abnormal beats than a lone PVC and can prompt closer evaluation for triggers like ischemia, electrolyte disturbances, or underlying heart disease, as well as more careful rhythm monitoring and management if needed.
