The infrahisian conduction system and endocavitary cardiac structures: relevance for the invasive electrophysiologist

摘要: With the increasing acceptability and use of catheterization ablation for ventricular tachycardia, detailed anatomic studies have been done to improve safety efficacy energy delivery in around critical cardiac structures [1–7]. More recently, fibrillation certain forms monomorphic tachycardia required either infrahisian conduction system or endocavitary structure, such as papillary muscle, false tendons, right moderator band [8–13]. In this review, we explain details structure structure–function relations tissue structures. We approach a single unit with routinely having rich network distal His-Purkinje system. addition, several commonly applied mapping maneuvers, including parahisian pacing pacemapping, rely on understanding anatomy active myocardium within cavity correct interpretation.
