A 64-year-old woman presented to the hospital with a complaint of dyspnea on effort. The 12‑lead electrocardiogram showed a baseline complete left bundle-branch block, in which the right bundle deve...
Electrocardiographic diagnosis of acute coronary occlusion can be difficult in the setting of left bundle branch block. If presumably new bundle branch block is considered equivalent to ST-elevation m...
This study sought to investigate how regional left ventricular (LV) function modifies septal motion in left bundle branch block (LBBB).
Conventional complete left bundle branch block (CLBBB) criteria sometimes result in a false-positive diagnosis that does not represent dyssynchrony. Recently, true CLBBB criteria have been proposed to...
Left bundle branch block (LBBB) is associated with a high risk of death, particularly from ventricular tachyarrhythmia and myocardial infarction. It is difficult to clinically differentiate between is...
The investigators sought to evaluate the morphological and functional changes, risk stratification and prognosis of patients of participants with compete left bundle branch block (CLBBB). ...
This study is to determine 1) the incidence of altered right bundle conduction, including CRBBB, IRBBB or rsR’ pattern in the Taipei city based on the school survey databank from 1999 to...
This is a prospective, single-arm, non-randomized, non-blinded study designed to characterize the locations of His Bundle (HB) pacing that results in correction of electrical dyssynchrony ...
Right ventricular pacing (RVP) causes left ventricular mechanical dyssynchrony by inducing electrical interventricular and intraventricular dyssynchrony. His bundle pacing may restore the ...
Ambulatory Electrocardiographic Monitoring for the Detection of High-Degree Atrio-Ventricular Block in Patients With New-onset PeRsistent LEft Bundle Branch Block After Transcatheter Aortic Valve Implantation. The "MARE" Study
The purpose of this study is to determine the incidence and predictors of high degree or complete atrioventricular block (AVB) (paroxysmal or persistent) in patients with new-onset persist...
A form of heart block in which the electrical stimulation of HEART VENTRICLES is interrupted at either one of the branches of BUNDLE OF HIS thus preventing the simultaneous depolarization of the two ventricles.
An autosomal dominant defect of cardiac conduction that is characterized by an abnormal ST-segment in leads V1-V3 on the ELECTROCARDIOGRAM resembling a right BUNDLE-BRANCH BLOCK; high risk of VENTRICULAR TACHYCARDIA; or VENTRICULAR FIBRILLATION; SYNCOPAL EPISODE; and possible sudden death. This syndrome is linked to mutations of gene encoding the cardiac SODIUM CHANNEL alpha subunit.
Impaired or delayed impulse conduction between the right and left HEART ATRIA. Advanced interatrial blocks are often associated with arrhythmias (e.g., ATRIAL FLUTTER; and ATRIAL FIBRILLATION), direct conduction block via the Bachmann's bundle and concomitant left atrial enlargement. Syndrome of advanced interatrial block associated with SUPRAVENTRICULAR TACHYCARDIA is referred to as Bayes syndrome.
Small band of specialized CARDIAC MUSCLE fibers that originates in the ATRIOVENTRICULAR NODE and extends into the membranous part of the interventricular septum. The bundle of His, consisting of the left and the right bundle branches, conducts the electrical impulses to the HEART VENTRICLES in generation of MYOCARDIAL CONTRACTION.
Interruption of sympathetic pathways, by local injection of an anesthetic agent, at any of four levels: peripheral nerve block, sympathetic ganglion block, extradural block, and subarachnoid block.
