目的验证重建心阻抗图测量左室射血分数（LEF）的可靠性。
Objective To Validte the Yeliabil of left ventricle ejection fraction(LEF) measured by reconstructed impedance cardiography(RICG).
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.
