简要总结

It's the aim of this study to investigate the impact of Right Ventricular (RV) lead position (RV-apex, His bundle area, RV-apex+His bundle area) in combination with individually optimized Left Ventricular (LV) lead placement and CRT timing on the outcome of cardiac resynchronization therapy (CRT).
