Left Bundle Branch Block: Characterization, Definitions, and Recent Insights into Conduction System Physiology.

Cardiology Clinics, 2023
Left bundle branch block (LBBB) is not just a simple electrocardiogram alteration. The intricacies of this general terminology go beyond simple conduction block.

The evolution of cardiac resynchronization therapy and an introduction to conduction system pacing: a conceptual review.

Europace, 2020
In chronic systolic heart failure and conduction system disease, cardiac resynchronization therapy (CRT) is the only known non-pharmacologic heart failure therapy that improves cardiac function, functional capacity, and survival while decreasing cardiac ...

Permanent conduction system pacing for congenitally corrected transposition of the great arteries: A Pediatric and Congenital Electrophysiology Society (PACES)/International Society for Adult Congenital Heart Disease (ISACHD) Collaborative Study.

Heart Rhythm, 2020
BACKGROUND Congenitally corrected transposition of the great arteries (CCTGA) is associated with spontaneous atrioventricular block and pacing-induced cardiomyopathy.

Cardiac transthyretin amyloidosis in patients with conduction system disease

European Heart Journal
Abstract Background/Introduction Cardiac amyloidosis (CA) is characterized by extracellular deposition of misfolded proteins in the heart. The data suggest that cardiac amyloidosis is underappreciated as a cause of common cardiac diseases or syndromes.

Electrophysiologic effects of intravenous magnesium in patients with normal conduction systems and no clinical evidence of significant cardiac disease

American Heart Journal, 1988
Parenteral magnesium has been used for several decades in the empiric treatment of various arrhythmias, but the data on its electrophysiologic effects in man are limited. We evaluated the electrophysiologic effects of magnesium sulfate (MgSO4) administration in eight normomagnesemic patients with normal mononuclear cell magnesium content, who had no ...

Comparison of 18F-fluorodeoxyglucose positron emission tomography (FDG PET) and cardiac magnetic resonance (CMR) in corticosteroid-naive patients with conduction system disease due to cardiac sarcoidosis

European Journal of Nuclear Medicine and Molecular Imaging, 2015
Cardiac sarcoidosis (CS) is a cause of conduction system disease (CSD). (18)F-Fluorodeoxyglucose-positron emission tomography (FDG PET) and cardiac magnetic resonance (CMR) are used for detection of CS. The relative diagnostic value of these has not been well studied.

[Steinert's disease with cardiac arrhythmia. Morphological findings in the heart conduction system].

Archivos del Instituto de Cardiologia de Mexico, 1975
This is a case report of a 63-year-old man with myotonic dystrophy in whom an ECG showed atrial flutter, complete A-V block, idioventricular rhythm with image of left bundle branch block and giant, wide and negative "T-U" waves. The microscopic study of the conduction system showed slight fibrosis of the SAN, fatty infiltration and cellular atrophy of ...

Defects in cardiac conduction system lineages and malignant arrhythmias: developmental pathways and disease.

Novartis Foundation symposium, 2004
To unravel the complex disease phenotype of heart failure, we are utilizing an integrative approach employing genomics, physiology, and mouse genetics to identify nodal pathways for specific physiological end points such as myocyte stretch activation responses, contractility and electrical conduction.

Conduction system disease management in patients candidate and/or treated for the aortic valve disease: an Italian Survey promoted by Italian Association of Arrhythmology and Cardiac Pacing (AIAC)

Acta Cardiologica
Conduction system disorders represent a frequent complication in patients undergoing surgical (surgical aortic valve replacement, SAVR) or percutaneous (transcatheter aortic valve implantation, TAVI) aortic valve replacement. The purpose of this survey was to evaluate experienced operators approach in this clinical condition.This survey was ...
