title: [Methods of 24-hour blood-pressure measurement].
abstract: With the recently growing use of portable devices for ambulatory blood pressure (BP) monitoring (ABPM), 24-hour BP measurement is often being performed even clinically. But such measurements as daytime BPs vary according to body position (sitting or standing) and motion (physical activity), ambient temperature, and the activities of the autonomic nervous system. Since it is capable of measuring all these factors (temperature, body position, acceleration, indirect BP, ECG and power spectral of heart rate variability) simultaneously, the multi-biomedical recorder (TM2425) we have developed is useful in objective evaluations of 24-hour BP values and its cause of BP variation. In addition, it is helpful in assessing minimal sleep-time BP (base BP) the most significant nighttime BP value.
