Intermittent automatic chronobiologic monitoring complements daily self-measurements.

The self-measurement of blood pressure for circadian rhythm assessment has been used for the evaluation, 'as one goes', of the effectiveness of treatment for high blood pressure (among other purposes). Even in a setting of high technology, with miniaturized ambulatory fully automatic recorders available, it is cost-effective to combine self- with automatic blood pressure measurement, to check on both the adequacy of treatment and the need for it. These aims were followed by an 81-year-old physician practicing autorhythmometry for over a decade.
