Figure 3 Accuracy of 2-Dimensional Radial Strain to Predict Response to Resynchronization Therapy
The receiver-operator characteristic curve analysis identified an optimal cutoff value to predict response to cardiac resynchronization therapy of 130 ms or more for left ventricular dyssynchrony reflected by an AS-to-P (AS-P) wall delay in 2-dimensional radial strain (RS). This cutoff value yielded a sensitivity of 83% with a specificity of 71%, with an area under the curve (AUC) of 0.75. Abbreviations as in Figure 2. Data from Delgado et al. (6).
