Functional aspects of His bundle physiology and pathophysiology: Clinical implications

His‐bundle pacing as a standard approach in patients with permanent atrial fibrillation and bradycardia

“…Permanent His‐bundle (HB) pacing emerged as a very promising method of truly physiological ventricular pacing . This method overcomes several drawbacks of the traditional ventricular myocardial pacing that includes introduction of iatrogenic left bundle branch block (LBBB)‐like interventricular asynchrony, pacing‐induced dilated cardiomyopathy, heart failure, tricuspid valve dysfunction, and retrograde conduction resulting in endless loop tachycardia, a need for programming long postventricular refractory period, and the perpetuation of atrioventricular block due to linking .…”

Bundle branch reentry with His dissociation—The His bundle: Bystander or participant?

“…In these studies, blunt trauma or ischemic injury to the His could lead to longitudinal dissociation (owing to disruption of transverse conduction within the His), which is marked by a split His recording. 9 , 10 , 11 …”

Conduction system pacing: overview, definitions, and nomenclature

“…The bundle of His is ∼1.8 cm long in an adult heart and is primarily located deep within the insulating tissue of the central fibrous body. 49 , 54 The central fibrous body adjoins the membranous septum and is a continuity between the aortic and mitral valves that extend rightwards to link with the septal tricuspid leaflet hinge line. The tendon of Todaro inserts into it at the apex of the Koch triangle ( Figure 1 ).…”
