Диссинхрония миокарда у больных с хронической сердечной недостаточностью: факторы, влияющие на развитие, особенности коррекции

Архивъ внутренней медицины, 2011
The purpose of our research was to study features of development of dyssynchrony in patients with heart failure and different forms of ischemic heart disease, and also to estimate efficiency of cardiac resynchronization therapy.

Biventricular Pacing during Cardiac Operations

The Heart Surgery Forum, 2005
Biventricular pacing (resynchronization therapy) improves the duration and quality of life in a subset of patients with congestive heart failure, but this technique has received little attention in the cardiac surgery literature. This report presents some preliminary ideas about its rationale and technique, and some likely indications for this ...

When Stability Fails: Rare Very Late Dislodgement of 3830 Lead

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT We report a rare case of very late dislodgement of a Medtronic SelectSecure 3830 lumenless lead three years after successful left bundle branch area pacing. An 88‐year‐old patient with permanent atrial fibrillation and bifascicular block underwent VVIR pacemaker implantation in 2022 with excellent initial parameters (threshold 0.8 V at 0.5 ms,

Ultra-High-Frequency ECG in Cardiac Pacing and Cardiac Resynchronization Therapy: From Technical Concept to Clinical Application

Journal of Cardiovascular Development and Disease
Identifying electrical dyssynchrony is crucial for cardiac pacing and cardiac resynchronization therapy (CRT). The ultra-high-frequency electrocardiography (UHF-ECG) technique allows instantaneous dyssynchrony analyses with real-time visualization.

Biventricular Pacing Cardiac Contractility Modulation Improves Cardiac Contractile Function via Upregulating SERCA2 and miR-133 in a Rabbit Model of Congestive Heart Failure

Cellular Physiology and Biochemistry, 2014
Objective: To compare the effects of biventricular electrical pacing and conventional single-ventricular pacing for cardiac contractility modulation (CCM) on cardiac contractile function and to delineate the underlying molecular mechanisms.

Effect of atrioventricular optimization on circulating N-terminal pro brain natriuretic peptide following cardiac resynchronization therapy. [PDF]

, 2013
AIMS: Following CRT, atrioventricular (AV) optimization is not routinely practised. To evaluate its clinical utility, we examined the effect of AV delay optimization on the prognostic biomarker NT-proBNP.

Cardiac Resynchronization Therapy: Reconsidering Its Essence as a Treatment for Electrical Dyssynchrony in Heart Failure

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
Flow of cardiac resynchronization therapy (CRT) in heart failure management. Heart failure (HF) patients with electrical dyssynchrony are first identified through screening. If electrical dyssynchrony contributes to HF deterioration, CRT is initiated to improve electrical synchrony.

Evidence of reverse remodeling after long-term biventricular stimulation for resynchronization in patients with wide QRS selected on the basis of echocardiographic electromechanical delays [PDF]

, 2004
Background. There is increasing evidence that cardiac resynchronization therapy (CRT) may trigger an inverse remodeling process leading to decreased left ventricular (LV) volumes in patients with heart failure and wide QRS. However, it is still important

Quality of life assessment in heart failure interventions: a 10-year (1996-2005) review. [PDF]

, 2007
The increasing prevalence and poor prognosis associated with heart failure have prompted research to focus on improving quality of life (QoL) for heart failure patients.
