What are two premature ventricular complexes (PVCs) in a row known as?

Two premature ventricular complexes (PVCs) in a row are referred to as a couplet. This terminology is rooted in the way these complexes manifest on an electrocardiogram (ECG). A couplet indicates that two consecutive PVCs occur without any normal beats in between, which can suggest a certain degree of cardiac irritability.

This term is widely used in the field of cardiology and helps healthcare providers communicate quickly and efficiently about arrhythmias. Understanding these terms is important for accurately interpreting ECG readings and determining appropriate clinical interventions. This is particularly relevant in monitoring patients with heart conditions where PVCs may be a concern.
