Figure 1 Normal 24 h ambulatory blood pressure recording. In all the figures, the simultaneous systolic and diastolic blood pressure values are connected by vertical lines. The blue line within the verticals is the mean blood pressure. The recorded pressure in mmHg is noted on the vertical axis. At the time of recording, recognized normal values, represented by light horizontal lines, were 135 mmHg systolic and 85 mmHg diastolic during the daytime and 120 mmHg systolic and 70 mmHg diastolic during sleep. The 24 h time of recording is noted on the horizontal axis. The solid black horizontal bar represents the sleep period.
