导纳法是在阻抗法基础上发展起来的又一种无创伤性检测心功能的方法。目前多认为其应用价值优于阻抗法。本文采用心导纳微分图多项指标对临床确诊为冠心病心绞痛患者做了检测,并与健康组进行对照,初步探讨了心导纳图各项指标的变化和冠心病心绞痛病变部位及范围的关系。 Admittance method is developed on the basis of the impedance method is another non-invasive method of detecting cardiac function. At present, many think its value is better than the impedance method. In this paper, cardiac admittance differential diagram of a number of indicators of clinically diagnosed as coronary heart disease in patients with angina pectoris were detected and compared with the healthy group, preliminary study of cardiac adduction changes in various indicators and coronary angina pectoris lesion location and range relationship.
