Intracardiac Delineation of Septal Conduction in Left Bundle-Branch Block Patterns: Mechanistic Evidence of Left Intrahisian Block Circumvented by His Bundle Pacing

Circulation, 2019
Background: Septal activation in patients with left bundle-branch block (LBBB) patterns has not been described previously. We performed detailed intracardiac mapping of left septal conduction to assess for the presence and level of complete conduction ...

Mortality in Patients With Right Bundle‐Branch Block in the Absence of Cardiovascular Disease

Journal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2020
Background Right bundle‐branch block (RBBB) occurs in 0.2% to 1.3% of people and is considered a benign finding. However, some studies have suggested increased risk of cardiovascular morbidity and mortality.

Atrioventricular reentrant tachycardia with a 2:1 right bundle branch block

Journal of Arrhythmia, 2012
The phenomenon of a 2:1 bundle branch block is reported during atrioventricular (AV) nodal reentrant tachycardia, sinus tachycardia, atrial fibrillation, and atrial flutter.

Possible Involvement of Coronary Microvascular Dysfunction in Painful Left Bundle Branch Block

JACC: Case Reports, 2023
Cases of painful left bundle branch block syndrome have been reported; however, the pathophysiology of chest pain remains unclear. Here, we report a patient with left bundle branch block and chest pain.

Masquerading Bundle Branch Block: A Poor Prognostic Sign Revisited [PDF]

Journal of Clinical and Diagnostic Research, 2016
Masquerading bundle branch block is a rare but important finding on the Electrocardiogram (ECG). It is an indication of severe and diffuse conduction system disease and usually indicates poor prognosis.

Clinical outcomes of left bundle branch pacing compared to right ventricular apical pacing in patients with atrioventricular block

Clinical Cardiology, 2021
Left bundle branch pacing (LBBP) can produce near normalization of QRS duration. This has recently emerged as alternative technique to right ventricular pacing and His bundle pacing.

Intra-His bundle block: clinical, electrocardiographic, and electrophysiologic characteristics

Arquivos Brasileiros de Cardiologia, 2002
OBJECTIVE: To assess the clinical, electrocardiographic, and electrophysiologic characteristics of patients (pt) with intra-His bundle block undergoing an electrophysiologic study (EPS).

Long-term outcomes of His bundle pacing in patients with heart failure with left bundle branch block

Heart, 2018
Objectives His bundle pacing (HBP) can potentially correct left bundle branch block (LBBB). We aimed to assess the efficacy of HBP to correct LBBB and long-term clinical outcomes with HBP in patients with heart failure (HF).

Differences in presentation and clinical outcomes between left or right bundle branch block and ST segment elevation in patients with acute myocardial infarction

European heart journal. Acute cardiovascular care, 2020
Background: In patients with acute myocardial infarction, the presence of a left bundle branch block or right bundle branch block may be associated with worse prognosis compared to isolated ST segment elevation.
