Receiver operating characteristic (ROC) curves for predicting response to cardiac resynchronization therapy (CRT). The area under the ROC curve (AUC) of R2-S/D coupling of Midseptal PS–Global volume loop was greater than that of TpPS-SD%, Tmsv-SD% and SDI (P < 0.05). SDI, strain delay index; Tmsv-SD%, standard deviation of time to minimum systolic volume corrected by R-R interval; TpPS-SD%, standard deviation of time to peak principal strain corrected by R-R interval
