摘要: Abstract Objectives To evaluate the long-term functional and hemodynamic effects of right ventricular outflow tract (RVOT) pacing by comparison with apical (RVA) pacing. Background Acute studies have suggested that RVOT could significantly improve cardiac performance in RVA but no data are available chronically implanted patients. Methods Sixteen patients chronic atrial tachyarrhythmia complete AV block were included. Left ejection fraction (LVEF) was ≥40% ten Results No significant difference observed between two modes for all parameters analyzed. These identical results globally, LVEF as those Conclusions Within limits this study, symptomatic improvement or benefit noted after three months pacing,
