Blood pressure variability assessed by semiautomatic and ambulatorily functional devices for home use.
As a basis for chronobiologic analyses and thereby for screening deviant blood pressure, measurements are advocated, preferably with ambulatorily functional instrumentation at half-hour intervals around-the-clock for an initial span of 7 days. When only manual instrumentation is available, 3-hourly measurements during waking and one measurement, preferably by a companion, around mid-sleep is recommended to detect a blood pressure disorder. Such screening is warranted for a reasonably reliable diagnosis, particularly in order to recognize circadian blood pressure overswinging (Circadian Hyper-Amplitude-Tension, CHAT) and to separate this new disease risk syndrome from an elevation of the time structure (chronome)-adjusted average (MESOR), that is MESOR-hypertension, and from the coexistence of the two foregoing conditions.
