WebFeb 18, 2014 · What is the rationale behind biventricular pacing in ventricular pacing-dependent patients with normal LV function? Right ventricular pacing induces interventricular and LV-intraventricular dyssynchrony similar to intrinsic left bundle branch block (LBBB).

Crossref Medline … WebPacing-induced cardiomyopathy (PICM) is most commonly defined as a drop in left ventricle ejection fraction (LVEF) in the setting of chronic, high-burden right ventricle (RV) pacing. Currently, very few effective treatments are standard for PICM which rely on the detection of the RV pacing.

WebOct 29, 2024 · Over the past 2 decades, there has been a resurgence of conduction system pacing (CSP) by implanting pacing leads in the His bundle region in lieu of chronic right ventricular pacing that is associated with worse clinical outcomes. WebChronic pacing from the right ventricular apex has been shown to result in left ventricular dysfunction. An alternative site, the RVOT septum, may provide more physiological activation of the ventricles and this site is now easily accessible, reliable and stable for lead placement.

WebChronic RV pacing causes ventricular dyssynchrony, which may lead to atrial and ventricular remodeling, mitral regurgitation, and diastolic and systolic dysfunction (see Figure 1 ). 1,2 Tolerance to chronic RV pacing appears to be influenced by baseline left ventricular (LV) function, the cumulative amount of ventricular pacing (VP), the … WebJan 1, 2010 · During this evolution, it has been noted that pacing from the right ventricular apex, even in the presence of high-grade AV block, may contribute to ventricular dysfunction associated with the disordered ventricular activation sequence associated with the paced left bundle branch block pattern.
