A premature ventricular complex is recognized on the ECG as an abnormal and wide QRS complex occurring earlier than expected in the cardiac cycle. It is caused by an impulse discharged from an ectopic focus which may be located anywhere in the ventricles.

A premature ventricular complex (PVC) is a premature beat arising from an ectopic focus within the ventricles. AKA: ventricular ectopics, ventricular extrasystoles, ventricular premature beats, ventricular premature depolarisations. ECG features of PVCs Broad QRS complex (≥ 120 ms) with abnormal morphology

During a premature ventricular contraction (PVC), the heartbeat is initiated by the Purkinje fibers rather than the SA node. Given that a PVC occurs before a regular heartbeat, there is a pause before the next regular heartbeat. PVCs can occur in isolation or in repeated patterns.

Premature Ventricular Complex: PVC marked by the arrow on an EKG in sinus rhythm. The compensatory pause is marked in blue. The ectopic impulses on the electrocardiogram are premature in relation to the expected impulse of the basic rhythm. The QRS complex is abnormal in duration and morphology.

Premature ventricular contraction couplets are extra, abnormal heartbeats that originating the Purkinje fibers of the ventricles. The PVC occur in pairs. Patients may feel a PVC as a skipped beat or palpitation. Single beat premature ventricular contractions are very common and can often be asymptomatic in healthy patients.
Ventricular Premature Beats - ECGpedia
https://en.ecgpedia.org/wiki/Ventricular_Premature_Beats
This ECG shows frequent premature beats from the right ventricular outflow tract A VPB is an ectopic beat that originates from the ventricles. VPBs are conducted by the specialized conduction system and therefore are broad. The QRS width is at least > 0.12 seconds, but often very broad at around 0.16-0.20 seconds.
Post-Exercise Premature Ventricular Contraction, or Aberrancy?
https://www.reliasmedia.com/articles/148934-post-exercise-premature-ventricular-contraction-or-aberrancy
It is common to see PVCs during exercise, especially if the degree of exercise is challenging for the patient. Although the much wider and different-looking appearance of the four early beats in the figure suggests these are PVCs, that is not the case. The underlying rhythm in this tracing is sinus at a rate of ~100 beats/minute.

Premature Ventricular Contractions (PVC’s) PVC’s are extra beats which occur from an ectopic focus on the ventricle wall. This focus is usually below the bifurcation of the bundle of HIS. In the normal person these may be caused by smoking, alcohol, or coffee ingestion. They usually are rare and inconsequential in normal persons.
