Early Deterioration of the Right Ventricular Pacing Threshold Predicts the Increase in His‐Bundle Pacing Threshold During the Chronic Phase: A Single‐Center Retrospective Study [PDF]

open access: goldJournal of Arrhythmia
Background His‐bundle pacing (HBP) facilitates physiological ventricular activation. However, concerns about long‐term threshold deterioration persist. The predictors of chronic threshold elevation are not yet well established.

The use of His bundle pacing for the treatment of painful left bundle branch block syndrome [PDF]

open access: goldClinical Case Reports, 2020
Painful left bundle branch block syndrome is a rare disorder in which patients develop typical angina‐like pain without identifiable ischemia. To date, there have been few published cases of effective treatment.

Fine Structure of the His Bundle [PDF]

open access: bronzeCirculation, 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.

Is Left Bundle Branch Pacing Feasible in Patients With Ventricular Septal Defect? [PDF]

open access: yesAnnals of Noninvasive Electrocardiology
His bundle typically passes through the central fibrous body of the atrioventricular node and then enters the membranous portion of the interventricular septum, where it branches into the left and right bundle branches. The feasibility and safety of left

Primer implante de electrodo de estimulación selectiva del haz de His en Colombia: Reporte de dos casos First implantation of selective his bundle pacing in Colombia: Report of two cases

open access: greenRevista Colombiana de Cardiología, 2010
Se conoce que la estimulación en el ápex del ventrículo derecho produce disincronía ventricular y muchas veces los pacientes desarrollan miocardiopatía dilatada, lo que ha llevado a realizar una estimulación más fisiológica.

Concealed WPW Syndrome with Longitudinal Dissociation in the His Bundle Exhibiting Five Different Electrocardiographic Waveforms During Tachycardia [PDF]

open access: goldJournal of Arrhythmia, 2005
We examined a patient with concealed WPW syndrome who exhibited five different electrocardiographic waveforms during tachycardia. With the intracardiac electrogram, all tachycardia were artrioventricular reciprocating tachycardia with retrograde ...

The Atrioventricular Conduction Axis Revisited for the 21st Century

open access: yesJournal of Cardiovascular Development and Disease, 2023
Although first described in the final decade of the 19th century, the axis responsible for atrioventricular conduction has long been the source of multiple controversies. Some of these continue to reverberate.

Catheter Ablation of Idiopathic Ventricular Arrhythmias Originating from the Para-Hisian area - QRS Morphology Change and Late Effect of the Ablation: Case Series [PDF]

open access: yesFolia Medica, 2020
Introduction: Radiofrequency catheter ablation of idiopathic ventricular arrhythmias originating in the para-Hisian region could be challenging because of a potential risk of iatrogenic atrioventricular block.

Anatomical variations and clinical significance of atrioventricular bundle of His: A concise literature review

open access: yesTranslational Research in Anatomy, 2023
Background: The cardiac conduction system (CCS) consists of the sinoatrial node, atrioventricular node, the atrioventricular bundle of His (HB), and its branches which terminate as subendocardial branches, also known as the Purkinje fibers.
