Since the classic study of Ayman and Goldshine [2], it has been recognized that the casual measurement represents a single measurement of blood pressure that reflects this constantly changing parameter to only a limited degree. Frequently altering conditions, especially the presence of a physician or nurse [9], lead to only limited reproducibility [1] of the casual blood pressure measurement, which nevertheless routinely enters into the establishment of the diagnosis and the decision for therapy and has been accepted and recommended by the World Health Organization (WHO) [21]. Apart from repeated measurements, home blood pressure measurement by the patients is particularly considered [8, 13] in order to obtain everyday representative blood pressure values. Continuous invasive intraarterial [10, 12] long-term techniques for blood pressure measurement, particularly the discontinuously measuring noninvasive procedures recently developed, now make it possible for us to analyze the blood pressure variability and the intraindividual circadian blood pressure technique in hypertensive ambulant patients under placebo [7], as well as under conventional [5] and new [15] antihypertensive therapy. |
