【摘要】 作者利用脉搏波传播特性检测系统及APPLE-Ⅱ微型机在线信号处理系统对生理及病理状态下脉搏波传播的时差特性和频谱特性进行分析。脉搏波的传播时差反映了动脉血管的弹性特性,是检测动脉硬化症的一个重要指标,脉搏波的自回归谱特性分析可为心血管疾病的临床诊断提供新的辅助依据。更多还原

【Abstract】 The authors measured the time interval between the radial artery pulse and carotid artery pulse in normal subjects and arteriosclerotic patients. The tests showed that time interval of wave propagation in arterial blood flow are related to the arterial elasticity. In diagnoses of cardiac and arterial diseases, the autoregression spectrum(AR spectrum) analyses of pulse signals are helpful.更多还原
