100例正常血压者24小时动态血压监测

24-hour ambulatory blood pressure monitoring in 100 normotensive subjects

非创伤全自动２４小时动态血压记录仪能测试不同环境、不同体位时病人的血压，显然优于人工偶测血压的方法。目前，因缺乏正常血压者的参考数据，使之在临床的应用受到很大限制。为此，我们做了１００例正常血压者的测试。结果显示：（１）２４小时动态血压均值，昼夜为１４．９／９．０ｋＰａ（１１２／６８ｍｍＨｇ），日间为１５．６／９．３ｋＰａ（１１７／７０ｍｍＨｇ），夜间为１４．４／８．５ｋＰａ（１０８／６４ｍｍＨｇ）。（２）如果以研究的各项平均值±２个标准差作为正常值范围，那么２４小时的动态血压均值正常分布范围，昼夜为１２．５～１７．３／７．４～１０．６ｋＰａ（９４～１３０／５６～８０ｍｍＨｇ），日间为１２．６～１８．５／７．７～１０．９ｋＰａ（９５～１３９／５８～８２ｍｍＨｇ），夜间为１２．０～１６．８／６．９～１０．１ｋＰａ（９０～１２６／５２～７６ｍｍＨｇ），２４小时测试数据最高值日间为２０．６／１２．６ｋＰａ（１５５／９５ｍｍＨｇ），夜间为１９．７／１１．８ｋＰａ（１４８／８９ｍｍＨｇ）。

Abstract Noninvasive ambulatory blood pressure monitoring (ABPM) is able to provide the patient's blood pressure ,(BP) data overday. It has been suggested that ABPM be superior to casual cuff methods in predicting cardiovascular events. We performed 24-hour noninvasive ABPM in 100 normotensive subjects. The results showed that the 24-hour BP averaged 112/68mmHg , the daytime BP 117/70mmHg and the nighttime BP 106/64mmHg. If the mean±2standard deviation interval were considered as the normal range of normal blood pressure, the average BP were 94-130/ 56-80mmHg over 24-hour,95-139 / 58-82mmHg for the daytime, and 90-126/52-76mmHg for the nighttime. And 155/95mmHg as the peak BP during daytime,1mmHg=0.133kpa
