Spontaneous variations of arterial cross section were recorded with impedance rheography (2 MHz) in 20 non-hypertensive subjects and in 23 patients with essential hypertension. The following parameters were measured in both groups: systolic blood pressure (SBP), diastolic blood pressure (DBP), cardiac period (Tc), intrinsic arteria period (Ta) and the ratio of Tc/Ta. Ta and Tc/Ta were significantly different in both groups (p < 0.01). The best discriminant variable was Tc/Ta. When used alone, it yielded an 88 % success in discriminating the subjects of each group. Frequency Fourier analysis showed significant differences between tha harmonic spectra of the two groups. These differences may be due to hypertension itself or to associated hypertension and pathologic disorders of the arterial wall. Their cause and effect relationship with arterial hypertension is discussed.
使用阻抗血流图(2兆赫)记录了20名非高血压受试者和23名原发性高血压患者动脉横截面的自发变化。在两组中均测量了以下参数:收缩压(SBP)、舒张压(DBP)、心动周期(Tc)、固有动脉周期(Ta)以及Tc/Ta比值。两组的Ta和Tc/Ta存在显著差异(p < 0.01)。最佳判别变量是Tc/Ta。单独使用时,它在区分每组受试者方面的成功率为88%。频率傅里叶分析显示两组谐波频谱之间存在显著差异。这些差异可能是由于高血压本身,或与高血压及动脉壁病理紊乱有关。讨论了它们与动脉高血压的因果关系。
