What is defined as two PVCs occurring in a row?

• A. Ventricular Triplet
• B. Ventricular Couplet
• C. Supraventricular Tachycardia
• D. Idioventricular Rhythm

Answer: (B)

The definition of two PVCs occurring in a row is known as a ventricular couplet. This term describes a situation in which two premature ventricular contractions happen consecutively without any normal beats intervening. Each PVC indicates a premature electrical impulse that originates in the ventricles rather than the sinoatrial node, which is responsible for initiating the regular heartbeat. The concept of a couplet is key in telemetry monitoring, as it highlights the occurrence of these two abnormal beats, which can signify underlying cardiac issues or irritability of the ventricular myocardium. Understanding and identifying a couplet is important for medical professionals as it can impact patient management and treatment decisions in the context of arrhythmias. The other options refer to different cardiac conditions or irregularities that do not specifically define the scenario of two consecutive PVCs. Ventricular triplet, for instance, involves three PVCs in succession. Supraventricular tachycardia is a rapid heart rhythm that originates above the ventricles, and idioventricular rhythm refers to a slow heart rhythm arising from the ventricles, typically without junction or atrial activity.
