Reduction of QRS amplitude correlates with decrease in left-ventricular pre-ejection time after cardiac resynchronisation therapy
ConclusionQRS width, but also QRS amplitude varies according to the pacing site after CRT and are correlated with left ventricular pre-ejection time. These ECG parameters could be helpful to optimize CRT.
