What is the prevalence and what are the clinical predictors of right ventricular dysfunction in patients with chronic right ventricular pacing?
Answers are grounded in this paper and cite their sources.
No results reported on RV dysfunction prevalence or predictors after chronic pacing; leaves open need for larger studies.
Background and Objectives: Numerous clinical studies have demonstrated chronic right ventricular (RV) pacing induced left ventricular (LV) dyssynchrony and LV systolic dysfunction in patients with permanent pacemaker. However, only a limited number of studies have focused on RV dysfunction. We sought to determine the prevalence and identify the clinical predictors of RV dysfunction in patients with chronic RV pacing. Subjects and Methods: We enrolled 72 patients (mean age 72.711.1 years, men 36.1%) who underwent permanent pacemaker implantation without RV dysfunction in baseline examination. Baseline clinical characteristics, laboratory data, echocardiographic parameters and pacing profiles were assessed. Follow up 2-dimentional echocardiography was used to identify the presence of RV dysfunction.
