What is the medical term for the event when two PVCs occur consecutively?

The term used to describe when two premature ventricular contractions (PVCs) occur consecutively is "couplet." This term is important in the field of cardiology as it helps in describing the frequency and organization of irregular heartbeats. When two PVCs appear in succession without intervening normal heartbeats, they create what is known as a couplet, which can be clinically significant in assessing a patient's cardiac rhythm and potential underlying conditions. Recognizing patterns such as couplets can help healthcare professionals in diagnosing arrhythmias and determining treatment options.

In contrast to couplets, a "pair" is a more general term and does not specifically refer to PVCs. A "run," typically refers to a sequence of three or more consecutive PVCs. Meanwhile, a "triplet" specifically describes three PVCs occurring in a row, which is a different pattern altogether. Understanding these terms contributes to a clearer communication regarding arrhythmias and aids in better patient management.
