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.
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。
Peaking effects were found on the plot of internal friction vs strain amplitude or time when the resonant frequency of anomalous peak closed to the normal one.
当反常共振峰频率与正常共振峰靠近时，在内耗-振幅或内耗-时间图上呈现峰值效应。
