N2 - In order to re-examine the extent to which secular circulatory variation can be resolved into possibly accountable, if not yet predictable behavior, the 15-year record of blood pressure and heart rate of an adult male cardiologist (Y.W.) is reanalyzed. Gliding spectral windows with an interval of 4 years progressively displaced throughout the data series examine monthly means from August 1987 to August 2002. A circannual variation is only intermittent and appears to drift for years. A circasemiannual variation is consistent and prominent, yet only for a fraction of the record examined. By contrast to the circadian rhythm in blood pressure and heart rate, which is reliably detectable in most subjects in clinical health, the circannual variation in the human circulation is inconsistent and hence should be monitored, as in this case for its assessment as one goes, a conclusion that also applies to the circasemiannual variation, prominent for years but not detected thereafter. The results prompt the search for interactions between the photic, thermic and societal effects of the seasons that, if solely pertinent, should yield a consistent 1-year spectral component. That non-photic effects may also play an important role may point to modulation by solar cycle stage and solar cycle number, perhaps mediated by the solar wind. This conclusion is extended in proof to the role played by the most recently discovered transannual component in human blood pressure and heart rate, which is a probable further signature of the solar wind. The beating of the transannual and circannual components documented on another data series may contribute to the lack of a consistent 1-year synchronized circannual variation in this case and many others.
