Triplet is defined as

Triplet is defined as

• A. Three consecutive normal beats
• B. Three consecutive PVCs
• C. Two consecutive PVCs
• D. One PVC followed by a normal beat

Answer: (B)

A run of three premature ventricular contractions in a row defines a triplet. Premature ventricular contractions are ectopic heartbeats that originate in the ventricles and appear as wide QRS complexes, often with no preceding P wave. When PVCs occur singly, it’s isolated ectopy; two consecutive PVCs form a couplet. Three consecutive PVCs, a triplet, indicate a higher burden of ventricular ectopy than a single event or a normal rhythm. This pattern is not three consecutive normal beats, nor is it one PVC followed by a normal beat. Recognizing three consecutive PVCs helps assess ventricular irritability and may prompt closer monitoring or further evaluation.
