“…A number of investigators worldwide have developed a chronobiologic approach to blood pressure evaluation and diagnosis. 24,[29][30][31][32][33][34][35][36][37][38][39] Blood pressure and heart rate data are collected by automatic ambulatory monitoring every 15 or 30 minutes over a 24-hour, 48hour, 72-hour, or preferably 7-day period. This allows the clinician to have sufficient data to be computer analyzed with chronobiology formulas that show the circadian pattern of the individual's blood pressure.…”
