无创性检测方法用来了解心脏功能作为估价药物疗效和预后的指标,其价值是肯定的,心阻抗微分图(dz/dt)的应用,已有较多学者肯定。1979年广西部分地区198644人心肌病普查,患病率达57.78/10万,为了探索无创性检查研究心肌病,本文通过99例正常人及40例原发性扩张型心肌病(DCM)阻抗微分图的对比分析,以了解DCM的dz/dt的改变。
Noninvasive detection method used to understand cardiac function as an index to evaluate the efficacy and prognosis of drugs, its value is positive, the application of cardiac impedance spectroscopy (dz / dt), more scholars have affirmed. In 1979 Guangxi part of the 198,884 cases of cardiomyopathy survey, the prevalence rate of 57.78 / 100 000, in order to explore the noninvasive examination of cardiomyopathy, 99 cases of normal and 40 cases of primary dilated cardiomyopathy (DCM) impedance differential Comparison of plots to understand DCM dz / dt changes.
