本文用上海医用电子仪器厂生产的 S(?)-42型四通道生理记录仪,配接恒流式直接记录阻抗导纳插件,同步记录冠心病患者和健康人的心电图、心音图和左心前区阻抗微分图(LV(?)),纸速为100mm/s。受检的冠心病患者45人,男33,女12,年龄44-72岁,平均年龄58岁,其中稳定性心绞痛28例,不稳定性者17例,健康人(正常组)共40例,男24,女16,年龄40-65岁,平均55岁。结果显示:1.正常组与稳定性心绞痛所测值对比中,等容舒张期(IRP)、快速充盈期(RFT)和早期舒张时间(EDT)的测值有着显著差异(P<0.05),但房缩期(AST)的差异不明显。1.正常组与不稳定心绞痛各指标相比,IRP、RFT 和 EDT 均有非常显著
In this paper, the S (?) - 42 four-channel physiological recorder produced by Shanghai Medical Electronic Instrument Factory was used in conjunction with a constant current direct recording impedance admittance plug-in to simultaneously record the ECG, phonocardiogram and left heart of patients with coronary heart disease and healthy people Impedance front differential plot (LV (?)), Paper speed of 100mm / s. Forty-five subjects with coronary heart disease were male 33, female 12, aged 44-72 years, with an average age of 58 years, of whom 28 were stable angina, 17 were unstable, and 40 were healthy (normal group) Male 24, female 16, aged 40-65 years, mean 55 years old. The results showed that there was significant difference (P <0.05) between the normal group and the stable angina measured value, the values of IRP, RFT and EDT, However, the difference between house contraction (AST) is not obvious. 1. Normal group and unstable angina indicators compared to IRP, RFT and EDT were very significant
