我们获得了多个动态血压监测（ABPM）的记录，超过五年，从两个训练有素的，血压正常的受试者在佩戴设备的经验。收缩压（SBP）、舒张压（DBP）和心率（HR）的时间序列数据用于建议两种仪器（Colin Medical Instruments ABPM-630和德尔马尔航空电子压力计）监测的最佳参数，并比较两种间接方法（听诊和血压计）。一个10分钟的采样间隔白天和黑夜提供了足够的数据密度，以支持频谱分析的超日节律的频率范围内的一个周期每小时到一个周期每9小时的24小时的记录。主要周期约为3，6，9小时的节奏不同地发现在94个血压正常的主题，年龄在20至95岁，包括两个训练有素的主题。当监测时间延长到72小时，昼夜节律（24小时）可以更清晰地定义，以及12小时谐波。在一些研究中，两个受过训练的受试者戴着两个显示器，每个手臂上一个，设置为同时阅读。从双臂同时测量，它表明，平均跨越三个点（30分钟的记录）减少两个同时记录之间的变异系数为6%或更少。听诊和听诊法同样可靠。超声心动图的数据，在5个血压正常的受试者，并比较他们的ABPM数据。ABPM记录提供了关于心血管功能的额外信息，而不仅仅是重复通过急性应激试验（如运动或冷加压反应）或超声心动图获得的信息。提出了动态血压监测的标准。
We obtained multiple ambulatory blood pressure monitoring (ABPM) records over five years from two trained, normotensive subjects experienced in wearing the apparatus. The resulting time series data on systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were used to suggest optimal parameters for monitoring by two instruments (Colin Medical Instruments ABPM-630 and Del Mar Avionics Pressurometer) and to compare two indirect methods (auscultatory and oscillometric). A 10-min sampling interval day and night provided sufficient density of data to support spectral analysis for ultradian rhythms in the frequency range of one cycle per hour to one cycle per 9 h on a 24-h record. Rhythms with major periods of approximately 3, 6, and 9 h were variously found in 94 normotensive subjects, aged 20 to 95 years, including the two trained subjects. When the monitoring period was extended to 72 h, the circadian (∼24 h) rhythm could be more sharply defined, as well as a 12-h harmonic. In some studies the two trained subjects wore two monitors, one on each arm, set to read simultaneously. From the simultaneous measurements on both arms, it was shown that averaging across three points (30 min of record) reduced the coefficient of variation between the two simultaneous records to 6% or less. Auscultatory and oscillometric methods were equally reliable. Echocardiographic data were obtained in five normotensive subjects and compared to their ABPM data. The ABPM records provided additional information about cardiovascular function not merely duplicating that obtained by acute stress tests, such as exercise or cold pressor responses, or echocardiography. Standards for ABPM are suggested.
