ROC curve areas for parameters of systolic asynchrony that predict LV reverse remodelling
| Parameter | ROC area (95% CI) | p Value | Cut-off value (ms) | Sensitivity (%) | Specificity (%) |
|---|---|---|---|---|---|
| Dif-12, maximum difference of measured timing between any two of 12 left ventricular (LV) segments; ROC, receiver operating characteristic; SD-12, SD of measured timing of the 12 LV segments. | |||||
