EKG

Ventricular Fibrillation:
Random electrical activity with no recognizable QRS complexes

Premature Ventricular Contraction:
Ectopic ventricular pacemaker inserts an ectopic beat = wide and bizarre QRS complex before the next sinus beat occurs

Ventricular Tachycardia:
Wide and bizarre but recognizable QRS complexes occur at an accelerated rate
