Table 3 ROC analysis for CRT response

From: Speckle tracking echocardiography analyses of myocardial contraction efficiency predict response for cardiac resynchronization therapy

Variable AUC cut-off Sensitivity (%) Specificity (%)
Predictors of non-response
 ECTR 0.682 59.02% 85.0 58.8
 ECR 0.724 62.68% 85.0 52.9
Predictor of response
 MLS 0.694 8.81 70.0 76.5
  1. ECTR the ratio of effective contractile time, ECR the ratio of effective contraction, MLS maximum longitudinal strain
