Functional characteristics of left ventricular synchronization via right ventricular outflow-tract pacing detected by two-dimensional strain echocardiography

Journal of Arrhythmia, 2017
Background: Recently, due to the detrimental effects on the ventricular function associated with right ventricular apical (RVA) pacing, right ventricular septal (RVS) pacing has become the preferred pacing method.

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Adverse effects of intracardiac dyssynchrony and right ventricular pacing on contractile function and prognosis

Российский кардиологический журнал
Pacemaker-induced cardiomyopathy (PICM) is a complication of frequent right ventricular pacing, which in most studies is regarded as a decrease in the left ventricular ejection fraction with constant right ventricular pacing.

Successful resynchronization by permanent His-bundle pacing in a patient with pacing-induced cardiomyopathy

Journal of Arrhythmia, 2016
Right ventricular (RV) pacing has been reported to result in ventricular dyssynchrony, heart failure, and increased mortality. Pacing associated deterioration of left ventricular (LV) systolic function has been termed pacing-induced cardiomyopathy (PICM).

Pacing the right ventricular outflow tract septum

EP Europace, 2012
We read with interest the article by Hillock and Mond1 in the January 2012 issue of the EP-Europace Journal. The authors make an extraordinary review of the always interesting and controversial topic of alternative pacing sites, focusing on right ventricular (RV) septal pacing.

Structural heart disease, not the right ventricular pacing site, determines the QRS duration during right ventricular pacing

Heart and Vessels, 2021
Right ventricular (RV) pacing causes changes in the heart's electrical and mechanical activation patterns. The QRS duration is a useful surrogate marker of electrical dyssynchrony; a longer QRS duration during RV pacing indicates poor prognosis.

CK2α Deficiency Drives Myocardial Fibrosis via Desmin‐Induced Mitochondrial Dysfunction

Advanced Science, EarlyView.
CK2α preserves mitochondrial homeostasis by phosphorylating Desmin to recruit Cryab, ensuring proper filament assembly. CK2α deficiency disrupts this interaction, causing mitochondrial dysfunction, metabolic shifts, bioenergetic failure, and oxidative stress—ultimately establishing a pro‐fibrotic environment that drives cardiac fibrosis.

Permanent Parahisian Pacing

Indian Pacing and Electrophysiology Journal, 2007
Right Ventricular Apical permanent pacing could have negative hemodynamic effects. A physiologic pacing modality should preserve a correct atrio-ventricular and interventricular synchronization.

Electrocardiographic and Skin Manifestations of Turner Syndrome: Association With Cardiovascular Disease

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Congenital heart disease (CHD) and dermatologic conditions such as lymphedema and acquired melanocytic nevi (AMN) are common in Turner Syndrome (TS). We hypothesized that abnormalities of cranial neural crest cell derivatives drive the skin and heart manifestations of TS. We conducted joint cardiac and skin examinations of volunteers at a 2023
