根据早搏后的正变力作用的原理和心肌力学的规律,采用心阻抗一阶导数图结合微电脑研究有室早的健康人22例和器质性心脏病病人22例,以探索两者之差异,结果两组室早前后的 QS_1、QZ、Cdz/dtmax、HI、SV、SW、PEPI、LVETI、PEPI/LVETI 有显著差异(P<0.001),而健康组的室早前后无明显差异(P>0.05),证明器质性心脏病室早后有明显的正变力作用,为临床鉴别诊断增添了新的重要内容。本方法无创伤、简便、安全、实用。
According to the principle of premature beat and the principle of cardiac muscle mechanics, 22 patients with healthy early heart disease and 22 patients with organic heart disease were studied using the first derivative of heart impedance combined with microcomputer to explore the difference between the two Results There were significant differences in QS_1, QZ, Cdz / dtmax, HI, SV, SW, PEPI, LVETI and PEPI / LVETI between the two groups before and after treatment (P <0.001) > 0.05), proves that the organic heart disease room has obvious positive change effect, added a new important content for clinical differential diagnosis. This method is non-invasive, simple, safe and practical.
