Association between left ventricular lead position and intrinsic QRS morphology with regard to clinical outcome in cardiac resynchronization therapy for heart failure
BackgroundLeft ventricular (LV) lead position may be an important factor for delivering effective cardiac resynchronization therapy (CRT). We therefore aimed to evaluate the effects of LV lead position, stratified by native QRS morphology, regarding the clinical outcome.MethodsA total of 1295 CRT-implanted patients were retrospectively evaluated. LV lead position was classified as lateral, anterio
