Effect of Rosuvastatin on Cardiac Function and Cytokines in Patients with Dilated Cardiomyopathy Antagonism for different doses of taurine on calcium overload in myocardial cells of diastole heart failure rat model 瑞舒伐他汀对扩张型心肌病患者心功能及细胞因子的影响牛磺酸对舒张性心力衰竭大鼠心肌细胞钙超载的拮抗作用
With CPA-2 cardiovascular analyzer, the cardiac systole function, cardiac diastole function, left ventricular time interval, and vascular function have been detected. 方法··:利用CPA-2分析仪,对心脏收缩功能、舒张功能、左室收缩时间间期和血管功能等内容进行了检测。
In the time sequence of cardiac myocyte beating images, the images of every systole/ diastole period are correlated. 在心肌细胞搏动的时间序列图象中,每个收缩/舒张周期的图象具有较大的相关性。
In the dynamic heart model, the coupling of electrical excitation and mechanical contraction were considered, and the resulted relative position changes between heart wall and body surface during cardiac systole and diastole were employed to calculate body surface ECG afterwards. 在动态心脏模型中考虑了心肌电兴奋引起的心脏机械力学收缩,通过计算心动周期中心室壁的位移,从而将心脏与体表之间的相对距离变化考虑进体表电位计算过程。
K is defined as the ratio of cardiac period ( T) to total duration of diastole ( Td). 时间因子K定义为心动周期(T)与舒张期持续时间(Td)之比。
Under some given conditions, the results showed: 1.The cardiac rupture happened at the end of diastole more often than that at the end of systole; 结果表明一定条件下:舒张末期较收缩末期易发生心脏破裂伤;
The simulation testing indicates that the cardiac surface motion model of the finite element method can intuitively and effectively reflect the strain distribution and deformation of the cardiac surface during systole and diastole. 仿真实验表明,基于有限元方法的心脏表面运动模型能直观有效地反映心脏表面在整个心脏收缩舒张的应变分布和形变情况。
