The His Bundle Electrogram [PDF]
Circulation, 1973 The His bundle electrogram is discussed with respect to its rationale, methods for its recording and evaluation, findings with its use in the various forms of heart block and arrhythmias, its clinical value, and its limitations.

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]
Journal of ArrhythmiaBackground 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.

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

Battery longevity and His bundle lead performance in His bundle pacing. [PDF]
Heart Rhythm O2BACKGROUND: High capture thresholds and lead dislodgment are often cited as impediments for general adoption of His bundle pacing. OBJECTIVE: We report on our experience in managing patients who underwent His bundle pacing with higher energy requirement and incidence of lead dislodgment in a mean duration of 33 months. METHODS: In 1188 patients, pacing

Journal of Interventional Cardiac Electrophysiology, 2018 His bundle pacing (HBP) has recently emerged as a technique to avoid the negative effects of long-term right ventricular apical pacing. In addition to providing physiologic ventricular activation, HBP has been shown to correct underlying conduction abnormalities in certain patients.

The Atrioventricular Conduction Axis Revisited for the 21st Century
Journal 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]
Folia 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.

Translational 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.
