[The origin of the biological week from data on the rhythm of cardiac contractions in people during the solar activity cycle].
A human biologic week in the heart rate variations was compared with the variations of the sunspot area and geomagnetic activity over the solar cycle. The low ratio of amplitude of circaseptan rhythm to that of circadian rhythm in the heart rate of several clinically healthy men who did around-the-clock self-measurements in a number of years coincides with the period of anomalously low amplitude of circaseptan rhythm of the solar activity. Results herein suggest that physiologic circaseptan rhythms are built into the genome being adapted evolutionary to the original heliogeomagnetic environmental circaseptans.
