摘　　要：目的:观察不同证候的冠心病患者动态心电图散点图特征,探索冠心病虚实证候与心率变异性混沌特征的相关性。方法:选取符合冠心病诊断的100例患者,观察其动态心电图中Lorenz散点图的形态、长轴、短轴、SD1/SD2(宽/长)、面积、矢量长度及矢量角度指数,将以上参数与患者的证候进行对比分析。结果:动态心电图Lorenz散点图图形对比显示,实证组呈现棒球拍和类棒球拍状的图形多于虚证组和虚实夹杂证组,而虚证组、虚实夹杂证组呈现扩张状及细棒状多于实证组(P>0.05)。虚、实、虚实夹杂三组在图形量化指标上对比显示,虚证组动态心电图Lorenz散点图图形长轴、短轴、SD1/SD2及图形面积都大于实证组(P<0.05),虚证组Lorenz散点图矢量长度指数和矢量角度指数大于实证组(P>0.05)。结论:冠心病虚实证候之间的冠心病Lorenz散点图长轴、短轴、SD1/SD2及图形面积等指标有显著差异,提示冠心病实证患者心率变异性较虚证患者显著下降。Objective Observing the Holter Scatter Diagram character which the TCM syndrome of CHD has,discover the Chaos character of TCM syndrome.Methods We grouped one hundred CHD cases who were diagnosed as CHD into the excessive syndrome and the deficient syndrome,taken HRV tests and done HRV nonlinear analysis simultaneously.Results The two groups were com-pared the Scatter Diagram long axis,Short axis,SD1/SD2,area,the difference was statistically significant （P〈0. 05）.Other Scat-ter Diagram parameter compared,the difference was not statistically significant （P〉0. 05 ）.Conclusion Use this method we can dis-criminate the syndromes of TCM who has CHD.HRV theory of nonlinear characteristics can provide basis to prevention and treatment of coronary heart disease.
