Figure 7 SPECT Prediction of Response to Resynchronization
Summed rest score (SRS) on SPECT predicted echocardiographic response rate after cardiac resynchronization therapy. The hazard ratio for nonresponse with SRS  27 is 3.59 (95% confidence interval 1.63 to 7.91; p < 0.0001). SPECT = single-photon emission computed tomography.
