用12个区域来测量收缩期圆周应变时间和应变率，并用应不峰值时间和应不率的标准差来表示心肌不同步。
Time to peak systolic circumferential strain and strain rate were measured in 12 segments, and myocardial dyssynchrony was expressed as the SD of time to peak strain and strain rate.
结果冠心病病人缺血心肌的收缩期峰值应变表现为明显减低、消失，甚至倒置。
Results Peak systolic strain of ischemic myocardium in patient with CHD was significantly lower, disappeared, or even showed inversion.
