Why the study?
Does right ventricular pacing alter right ventricular echocardiographic function parameters in adult patients with indications for permanent pacemakers?
Does right ventricular pacing alter right ventricular echocardiographic function parameters in adult patients with indications for permanent pacemakers?
Right ventricular pacing generally worsens right ventricular function, with apical pacing having the most detrimental echocardiographic effects, whereas left bundle branch area pacing (LBBAP) appears to preserve RV function more effectively.
Answers are grounded in this paper and cite their sources.
LBBAP should be considered over apical pacing for ventricular stimulation; extends prior LV evidence to RV echocardiographic function.
RV pacing is associated with significant reductions in S' and notable effects on other echocardiographic parameters, with heterogeneity largely driven by the site of pacing. Apical pacing had the most detrimental effects across multiple parameters, whereas LBBAP was generally associated with better outcomes. Further studies are needed to address residual heterogeneity and examine additional covariates.
