Circadian Rhythms of the Circulatory System. Literature Review: Computerized Case Study of Transmeridian Flight and Medication Effects on a Mildly Hypertensive Subject.

Abstract

Rhythmic changes in blood pressure are assessed by flight surgeons and other medical practitioners by considering separately the systolic as compared to the diastolic measurements. Predictably recurring pressure changes other than those associated with the heartbeat also have long been known and await exploitation in practice. This report: (1) reviews the literature in the field of circadian circulatory rhythms; (2) specifies causes delaying clinical progress in application of circadian rhythmometry; (3) indicates with an illustrative example how modern computer techniques have started to overcome some of the difficulties encountered in quantifying and interpreting and interpreting rhythms; and (4) demonstrates effects stemming from intercontinental transmeridian flights upon several circadian rhythms in a mildly hypertensive subject.
