目的探讨应用三维彩色室壁运动(CK)技术测量梗死区和非梗死区心搏量和射血分数的方法。
Objective To develop a new method for measuring stroke volume and ejection fraction in the infarct and non infarct area with three dimensional color kinesis (CK) technique.
心输出量增加，心脏收缩加强能泵更多的血液，心搏量增加，左心室壁变厚(更多肌肉)，心脏对氧气的需要减少。
Increases Cardiac Output, stronger heart contractions pump more blood, increased stroke volume, thickens left ventricle wall (more muscular), decreases hearts' oxygen requirements.
结果表明，用线性回归模型计算的左室射血分数、每搏量、心输出量在较低心率时模拟数值较为可信，在较高心率时每搏量模拟数值不可靠。
It showed that the simulation results of LVEF, SV and CO were reliable at a low heart rate with linear regression model, but unreliable at a high heart rate.
结果：两组患者心排血量（CO）、心脏指数（CI）、每搏量（SV）和每搏指数（SI）等指标在硬膜外阻滞平面固定后均有明显下降。
Results: Cardiac Output (CO), Cardiac Index(CI), Stroke Output(SV) and Stroke index(SI) in two groups were significantly decreased when the sensory levels were finally distributed to T_6-S.
