Ventricular Arrhythmia

Ventricular arrhythmia (pronounced ven-TRIK-yoo-lur uh-RITH-mee-uh) is a term for any rhythm disorder originating in the lower chambers of the heart, known as the ventricles.

Etymology

The term "ventricular" is derived from the Latin word "ventriculus", which means "little belly". It refers to the ventricles of the heart, which pump blood out of the heart. "Arrhythmia" is derived from the Greek words "a-", meaning "not", and "rhythmos", meaning "rhythm". Thus, "arrhythmia" refers to a lack of rhythm or regularity.

Definition
