【摘要】 应用无创性全自动２４小时动态血压监测技术，对７０例老年人测试，其中男性４４例，女性２６例；分正常血压组和轻中型高血压两组观察。分析结果：正常血压组和轻中型高血压组昼夜血压波动规律明显不同，前者呈日间上升、夜间下降趋势；后者呈双峰双谷状。波动范围亦不同，前者收缩压波动范围＜６．６７ｋＰａ（５０ｍｍＨｇ），舒张压＜５．５３ｋＰａ（４０ｍｍＨｇ）；后者收缩压波动范围＞６．６７ｋＰａ（５０ｍｍＨｇ），舒张压＞５．５３ｋＰａ（４０ｍｍＨｇ）。两组２４小时动态血压均值范围参考数据有明显差异。如果以各项研究均值＋２个标准差为上限值，老年人正常血压者２４小时动态血压监测数据，日间最高不应＞２１．２／１２．５ｋＰａ（１５９／９４ｍｍＨｇ），夜间不应＞１９．６／１２．０ｋＰａ（１４７／９０ｍｍＨｇ）。更多还原

【Abstract】 Using non-invasive ambulatory blood pressure(BP) monitoring technique measured the BP of old-age patients(70 yrs.,44 men and 26 women) who were divided into normotensive and mild-to-moderate hypertensive groups.The result showed that there was marked difference in circadian rhythym.The BP of normotensives rose during daytime and fell at night,and that of the mild-to-moderate hypertensives had two peaks and two valleys.The changing ranges were also different,systolic pressure(SP) was less than 6.67 kpa(50 mmHg) and diastolic pressure(DP) less than 5.53 kpa(40 mmHg) in the former;while SP was more than 6.67 kpa(50 mmHg) and DP more than 5.53 kPa(40 mmHg) in the latter.In the normotensive group,Twenty four hour ambulatory BP was 14.1-16.3/8.13-8.93 kPa (106-122/61-67 mmHg) with daytime BP of 14.4-17.118.13-9.60 kPa(108-128/61-72 mmHg) and nighttime BP of 13.1-15.5/7.47-8.53 kPa (98-116/56-64 mmHg);in the hypertension group,they were 18.2-19.8/10.0-11.3 kpa(137-149/75-85 mmHg),17-7-20.7/10.3-11.3 kPa(133-155/77-86 mmHg),and 17.7-18.8/10.1-10.9 kpa(133-141/76-82 mmHgl,respectively.With mean±2 standard deviation as upper limit, for old-age normotensives,the highest BP should be less than 21.2/12.5 kpa(159/94 mmHg) and 19. 6/12.0 kpa(147/90 mmHg) for daytime and nighttime,respectively.更多还原
