摘　　要：采用心导纳图法分析了６６例，三种不同血压组患者（其中正常血压组３２例、低血压组１１例和高血压组２３例）的总外周阻力、血管顺度（亦称血管顺应性）及左心射血功能的变化。结果发现，高血压组总外周阻力明显高于低血压组和正常血压组（Ｐ＜０．０１），血管顺度明显降低（Ｐ＜０．０１），且与脉压差呈显著的负相关（ｒ＝－０．７２，Ｐ＜０．０１）。随着血压的升高，每搏输出量及导纳微分环上射血面积显著下降（Ｐ＜０．０１）。结果提示，心导纳图法在分析高血压病及高血压心脏病中具有重要的临床意义。Admittance cardiograghy was applied in the analysis of the changes in total peripheral resistance (TPR),vascular compliance (C) and left ventricular pump functin in 66 people,including 32 with normal,11 with low and 23 with high blood pressure.It was found that TPR was significantly higher and C significantly lower in patients with high blood pressure than those with normal and low blood pressure ( P <0.01),and the decrease in C was negatively correlatd with pulse pressure (△P) in patients with high blood pressure (r= 0.72, P < 0.01 ).Together with the rise of blood pressure,the stroke volume (SV) and ejection area in the admittance differential loop decreased significantly.These results indicate that the method of admittance cardiography is of important clinical value in the analysis of hypertension and hypertensive heart diseases.
