Left posterior fascicular ventricular tachycardia in a young infant with a structurally normal heart: Clinical course and caveats to electrocardiographic diagnosis

J Electrocardiol. 2021 Jan-Feb:64:85-90. doi: 10.1016/j.jelectrocard.2020.12.003. Epub 2020 Dec 11.

Abstract

In this illustrative case report, we describe a rare case of left posterior fascicular ventricular tachycardia (LPFVT) in a 2 month-old infant with emphasis on electrocardiographic caveats to diagnosis. The clinical course, treatment, and eventual resolution of the VT over a 2 year follow-up is comprehensively compared and contrasted to a modicum of individual such case reports of infants. The corpus of each such case of infantile LPVT is systematically reviewed and succinctly summarized in a tabular compendium. The collective knowledge compiled here should allow for a refined approach to diagnosis and management of this unusual arrhythmia.

Keywords: Infant; Left posterior fascicular ventricular tachycardia (LPFVT); Verapamil sensitive ventricular tachycardia.
