His Bundle Electrogram in Bundle-Branch Block [PDF]
Circulation, 1972 Because a great majority of patients with chronic complete heart block have bilateral bundle-branch lesions, it becomes important to recognize earlier degrees of bilateral bundle-branch block. The H-V interval in the His bundle electrogram during unilateral bundle-branch block reflects the conduction primarily through the contralateral bundle branch ...

Fine Structure of the His Bundle [PDF]
Circulation, 1971 The fine structure of the His bundle is described on the basis of its light and electron microscopic appearance. Electron microscopy was performed on one human and two canine hearts, and light microscopy on over 400 human and 60 canine hearts. The His bundle was identified by its light microscopic appearance.

His bundle lead placement: Is His bundle captured?
Pacing and Clinical Electrophysiology, 2020AbstractA 59‐year‐old female underwent a dual‐chamber pacemaker implantation for intermittent complete heart block. A baseline electrocardiogram showed normal sinus rhythm with first‐degree atrioventricular (AV) block and right bundle branch block. A His bundle lead placement was attempted.

Heart & Lung, 2005
In patients with narrow QRS complexes, atrioventricular block is usually localized to the AV node, and it is frequently benign. The more distal intra-His bundle blocks are rare, potentially malignant, and difficult to recognize. This case report illustrates how His bundle block can be diagnosed by analyzing the effects of certain maneuvers on the heart

Wilhelm His Junior and his bundle
Journal of Electrocardiology, 2016We have reviewed the evidence relative to the initial description of the penetrating atrioventricular bundle, seeking to determine whether Wilhelm His Junior is deserving of his eponym.

Bulletin der Schweizerischen Akademie der Medizinischen Wissenschaften, 1975
In this presentation the use of His bundle electrography in the diagnostic localization of atrioventricular conduction defects is discussed. The recording of the His potential allows an identification of conduction disturbances at a level above, in, or below the His bundle. Atrioventricular conduction can be stressed and latent conduction abnormalities

Antegrade Concealed Conduction to the His Bundle; Documentation with His Bundle Recording
Chest, 1974A patient had blocked interpolated premature atrial contractions, followed by P-R prolongation in the subsequent cycle, suggesting antegrade concealed conduction to the A-V node. His bundle recordings revealed this interpretation to be erroneous. The atrial premature beats were blocked distal to the H recording site.

Transvenous Cryoablation of the Bundle of His
Pacing and Clinical Electrophysiology, 1991Cardiac dysrhythmias are a prominent cause of morbidity and mortality. Pharmacological treatment is ineffective in a large number of patients and is associated with many serious side effects. Thus, direct treatment of cardiac arrhythmias has been used with increasing frequency.

Anatomical approach to permanent His bundle pacing: Optimizing His bundle capture
Journal of Electrocardiology, 2016Permanent His bundle pacing is a physiological alternative to right ventricular pacing. In this article we describe our approach to His bundle pacing in patients with AV nodal and intra-Hisian conduction disease. It is essential for the implanters to understand the anatomic variations of the His bundle course and its effect on the type of His bundle ...
