Predictors of short-term clinical response to cardiac resynchronization therapy [PDF]

, 2017
Aims: Cardiac resynchronization therapy (CRT) reduces morbidity and mortality in patients with symptomatic heart failure and QRS prolongation but there is uncertainty about which patient characteristics predict short-term clinical response.

Reversible T-wave inversions during left bundle branch area pacing

Kardiologia Polska, 2022
Our clinical observation found that T-wave inversions (TWIs) appeared during left bundle branch area pacing (LBBAP); however, the incidence and influencing factors were unclear. The study aimed to investigate the effects of LBBAP on T-wave and explore possible factors associated with TWIs.This was a retrospective cohort study. An electrocardiogram (ECG)

Left Bundle Branch Area Pacing Versus Biventricular Pacing as Initial Strategy for Cardiac Resynchronization.

JACC Clinical Electrophysiology, 2023
BACKGROUND Left bundle branch area pacing (LBBAP) for cardiac resynchronization therapy (CRT) is an alternative to biventricular pacing (BiVp). OBJECTIVES The purpose of this study was to compare the outcomes between LBBAP and BiVp as an initial ...

Clinical and Procedural Characteristics of Acute Hemodynamic Responders Undergoing Triple-Site Ventricular Pacing for Advanced Heart Failure [PDF]

, 2011
The advantages of triple-site ventricular pacing (Tri-V) compared to conventional biventricular site pacing (Bi-V) have been reported. We sought to identify the predictors of acute hemodynamic Tri-V responders. Acute hemodynamic studies were performed in

Mid‐term comparison of new‐onset AHRE between His bundle and left bundle branch area pacing in patients with AV block

Journal of Arrhythmia
Atrial high‐rate episodes (AHRE) detected by cardiac implanted electronic devices are known markers for adverse cardiac events. Previous studies have shown that the incidence of new‐onset AHREs in patients with right ventricular pacing reaches 50%.

Conduction system pacing in adults with congenital heart disease

International Journal of Cardiology Congenital Heart Disease, 2021
Conduction system pacing is a growing sub-speciality within electrophysiology and its use is expanding. We conduct a review of the current state of knowledge, evidence and future direction for conduction system pacing in adult congenital heart disease.

Idiopathic Fascicular Ventricular Tachycardia [PDF]

, 2004
Idiopathic fascicular ventricular tachycardia is an important cardiac arrhythmia with specific electrocardiographic features and therapeutic options. It is characterized by relatively narrow QRS complex and right bundle branch block pattern. The QRS axis

Concepts of Cardiac Dyssynchrony and Dynamic Approach

Diagnostics
Cardiac conduction involves electrical activity from one myocyte to another, creating coordinated contractions in each. Disruptions in the conducting system, such as left bundle branch block (LBBB), can result in premature activation of specific regions ...

Prognostic implications of left ventricular global longitudinal strain in heart failure patients with narrow QRS complex treated with cardiac resynchronization therapy: a subanalysis of the randomized EchoCRT trial [PDF]

, 2016
Aim: Left ventricular (LV) global longitudinal strain (GLS) reflects LV systolic function and correlates inversely with the extent of LV myocardial scar and fibrosis.
