| 中文摘要: |
| 本文研究发现老年患者四种动脉顺应性随年龄的增大而减低。弦脉的零压动脉顺应性 Co 最小,细弦脉的 Co 最大,弦滑脉的 Co 居中。弦滑脉的外周阻力接近弦脉,故认为弦滑脉以弦为主脉,滑为兼脉。老年患者血流动力学改变从近老年时就开始,其中外周阻力(R)增大,每搏心输出量(SV)的减低出现较早,而 Co 减低则出现较迟。 |
| 英文摘要: |
| This analysis of pulse patterns and hemodynamics was based on the data of 115 aged patients according to elastic chamber theory.All of the four kinds of arterial compliances(C)were found to he reduced with increasing of age,which was probably correlated to the increase of systolic pressure in the aged person.In 80～90 age-group,Co and stroke volume were smallest,and the peripheral resistance highest.In 70～79 age-group,the mean values of the above three parameters approached those of the entire aged group.Co of wiry pulse was smallest,which was relevant to the degree of arteriosclerosis,and to the high age,high systolic,diastolic and pulse pressure.In those manifested as fine wiry pulse,their mean systolic and pulse pressure were lower,and Co was greatest,therefore the arteriosclerosis was less severe. In another three pulse patterns,the changes in peripheral resistance were in consistency with those of mean systolic and diastolic pressure.The peripheral resistance of wiry smooth pulse approached that of wiry pulse,therefore,wiry pulse is the main component and smooth pulse is secondary.The hemodynamic changes in the aged started from pre-aging period,increase of peripheral resistance and decrease of stroke volume occurred early,whereas lowering of Co occurred late,its mean value appeared markedly reduced after 65 years of age.The sphygmograms of wiry pulse of the aged person can be classified into seven types,among which oblique-wide type is most common.The higher the position of the junction between the predicrotic and the main waves,the severer would be the degree of arteriosclerosis,and this is of prognostic significance. |
