It’s known as a premature ventricular contraction (PVC, also premature ventricular complex). When PVC happens in a pattern of three beats, doctors call it trigeminy. It can feel like fluttering ...

Therefore, the third QRS complex is also a sinus complex. There is a repeating pattern, and every third QRS complex is a premature ventricular contraction (PVC), representing ventricular trigeminy.

In this article, learn all about trigeminy, including how to identify it. This article will also cover the symptoms, causes, and treatments.

Recent 24 h Holter monitoring demonstrated a reduction in the number of premature ventricular complexes (PVCs) to 2,022, with 7 episodes of bigeminy and 121 of trigeminy recorded over this period.
