Özet

© 2022 Innovations in Cardiac Rhythm ManagementWe present a patient with ischemic cardiomyopathy who had ventricular tachycardia (VT) with QRS morphology alternans. The electrophysiological findings, in this case, supported the occurrence of antegrade activation of the proximal His–Purkinje system during VT, with the ultimate electrocardiogram morphology dependent on fusion from intramyocardial and His–Purkinje activations.
