Extrasystole
Ventricular Premature Contraction
A group of premature ventricular contractions in which the QRS configuration is always the same are referred to as monomorphic premature ventricular contractions.

Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of your heart's two lower pumping chambers (ventricles). These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a fluttering or a skipped beat in your chest. Premature ventricular contractions are common — they occur in many people. They're also called: Premature ventricular complexes Ventricular premature beats Ventricular extrasystoles If you have occasional premature ventricular contractions, but you're otherwise healthy, there's probably no reason for concern, and no need for treatment. If you have frequent premature ventricular contractions or underlying heart disease, you might need treatment.

It is a defective ventricular contraction.

The normal time of ventricular contraction depends on the heart rate. The QT segment represents the ventricular contraction on an ECG exam. The corrected QT segment is 0.45 seconds for men and 0.46 seconds for women.
purkinjie fiber develops a rhythm of its own & ventricular contraction occur
This is called the systole :)
