Fusion beats
Explanation:
Ventricular tachycardia or VT originates from the normal conduction system within the ventricle. It may caused by reentry circuit or increased automiticity. The majority of patients with VT have underlying cardiac disease.
Ventricular tachycardia is a type of fast regular heart rate which arises from the improper electrical activity which occurs in the ventricles of the heart.
Fusion beats occurs when impulses from the two different locations -- one in a supraventricular location and the other within the ventricle activates the ventricle. This results in QRS complex with a hybrid of intraventricular beat and a sinus beat
Thus Fusion beats is useful in diagnosis of the ventricular tachycardia.
