本文按NYHA心功能分级方级方法,选择心功能Ⅲ级的病人20例,其中冠心病15例,扩张型心肌病5例,所有病人在试验前停用血管扩张剂3天,于上午9:00—12:00时,同步进行心阻抗图与心导管连续性监测,其结果见表1与表2。表1.静息状态下阻抗法与Fick方法测定心排出量 In this paper, according to NYHA heart function grading square method, 20 patients with grade Ⅲ cardiac function were selected, including 15 cases of coronary heart disease and 5 cases of dilated cardiomyopathy. All patients discontinued vasodilators for 3 days before the test, 00-12: 00, simultaneous cardiac impedance map and cardiac catheter continuity monitoring, the results shown in Table 1 and Table 2.
