The left panels are bull eyes patterns of time to peak radial strain of left ventricle subdivided into 16 segments in control subject (a), recovered NDCM patient (c) and unrecovered NDCM patient (e). SD16-TTPRS was 60 ms, 76 ms and 158 ms, respectively. Compared with control subjects, the time gap was prolonged in recovered NDCM and was the largest in the unrecovered NDCM cohort. This led ineffective shift of blood and lower left ventricular stroke volume. The right panels demonstrated peak radial stain curves for synchronism, which showed homogeneity in control subject (b), less coincidence in recovered NDCM (d) and the most inconformity in unrecovered NDCM (f). The purple curve in each graph indicated the earliest segment reaching the peak radial strain, which was segment 7, 4 and 16, respectively. The left red arrow in each graph was the time the earliest segment reached the peak radial strain, whereas red arrow in the right was the time of the latest segment. The time gap gradually increased in healthy control subjects, recovered NDCM and unrecovered NDCM
