中文摘要:

本文报道对40例气(血)虚患者作心搏间距变化及卧立位血压差等无创伤性测定,并与100名正常人相对照。结果表明气(血)虚组与对照组在呼吸差、立卧差及30/15比值上相比较均有显著差异(P 均<0.01)。在卧立位血压差上两组也存在明显区别。反映气(血)虚患者存在着心血管植物神经系功能紊乱。该方法简便易行,可作为气(血)虚证临床观察的一项指标。

英文摘要:

Forty cases of Qi(vital energy)deficiency patients have been examined with the beat interval and the postural difference of blood pressure(horizontal and vertical posture),and in comparison with 100 normal cases in the same sex and age.Among these 40 cases,Qi deficiency was found in 33 cases and deficiency of Qi and blood in 7 cases.The Qi deficiency syndrome itself comprises of diseases of various systems. Results:(1)The variation of beat interval:With ECG,the heart rate during quiet states,the change of beat interval both during deep breathing(i.e.respiratory difference)and at the horizontal and vertical posture(i.e.postural difference)and the heart beat ratio at time 30 and time 15(30/15 ratio)of the patients were recorded.Except for the heart rate during quiet states(P>0.05),there were significant difference on respiration,postures and heart beat ratio(30/15)between the patients and control group(P<0.01).(2) Postural difference of blood pressure:The average postural difference of systolic blood pressure was 24.58 mmHg in 17 Qi deficiency patients(8 cases of which showed over 30 mmHg),while that of control group was 2.76 mmHg only(none of them above 30 mmHg).So the indices of the two groups were significantly different. It indicates that the functional disorder of vegetative nervous system do exists with involvement of sympathetic and parasympathetic disorder to some extent in the Qi deficiency patients.We consider that this test provides a valuable parameter for the clinical observation of Qi deficiency patient and give an important clue to explore the substantial basis of Qi and blood.
