Ventricular Fusion Beats
ECG Features
ECG Features
Figure 1: ECG Strip[1]
A fusion beat occurs when "a supraventricular and a ventricular impulse coincide to produce a hybrid complex."[2] A ventricular fusion beat or fusion PVC is produced when these electrical impulses coincide in the ventricular chambers. Fusion beats are seen with ventricular tachycardia (Figure 1) and accelerated idioventricular rhythm.[2]
