- The temporal-spatial distributions of hemodynamics during the cardiac cycle such as flow patterns and wall shear stress in the vicinity of anastomosis were analyzed. 计算结果分析了缝合区附近的流场、壁面剪应力等血流动力学因素在心动周期内的时空分布情况。
- The arterial flow during systole and early diastole was reersed, whereas the flow during late diastole at the end of the cardiac cycle was forward transiently. 在我们的病例中，左侧眼动脉远端频谱异常，在收缩期和舒张早期血流反向，而在舒张晚期血流瞬间向前。
- The software also provided with each of the above parameters as a percentage of the cardiac cycle:Tmsv16-SD%,Tmsv12-SD%,Tmsv6-SD%,Tmsv16-Dif%,Tmsv12-Dif% and Tmsv6-Dif%. 以上参数用心率校正后,分别为Tmsv16-SD%25、Tmsv12-SD%25、Tmsv6-SD%25、Tmsv16-Dif%25、Tmsv12-Dif%25及Tmsv6-Dif%25,结果与正常对照组进行比较。
- RCA and LCX moved less than 3 mm/NTU during mid-diastole (75% R-R ECG trigger-delay) and end-systole (40% R-R ECG trigger-delay). LAD moved less than 3 mm/NTU throughout cardiac cycle. 当心率小于 75bpm时 ,RCA和LCX在ECG触发延迟 75%25R R的舒张中期和40%25R R的收缩末期运动速度小于 3mm/NTU ,LAD在整个心动周期运动速度基本都小于 3mm/NTU。
- During the two cardiac cycle including the matching phase and the compensation phase of premature beat, the average work of left ventricle was decreased 9.0% by VPB, 3. 3 % by JPB and 3.0% by APB. 在配对间期和代偿问期两个心动周期中，一次室早、房早和交界性早搏分别使心脏减少作功9．0%25、3．0%25、3．3%25。
- High-energy FLASH frames destroyed bubbles every 15 cardiac cycles, and resultant time-intensity curves derived from these sequences were fitted to an exponential function as y = A(1-e -bt )+c from which the rate of signal rise (b) was obtained. 每 15个心动周期进行 1次破泡。 破泡后的再充盈时间 -强度关系可用公式y =A(1-e-bt) +c表示 ,依此可得到信号增加率b。
