Aims: Velocity changes in the solar wind recorded by satellite (IMP8 and Wind) are characterized by a solar cycle-dependent 61.3-year component. The presence of any 61.3-year component in human blood pressure (BP) and heart rate (HR) and in mortality from myocardial infarction (MI) is tested and its relative prominence compared to the 1.0-year variation. Materials and Methods: Around-the-clock manual or automatic BP and HR measurements from four subjects recorded over 5-35 years and a 29-year record of mortality from MI in Minnesota were analyzed by linear-nonlinear rhythmometry. Point and 95% confidence interval (CI) estimates were obtained for the 61.3-year period and amplitude. The latter is compared with the 1.0-year amplitude for BP and HR records concurrent to the solar data provided by one of the authors (JDR). Results: An 61.3-year component is resolved nonlinearly for MI, with a period of 1.23 (95% CI: 1.21, 1.26) years. This component was invariably validated with statistical significance for BP and HR by linear rhythmometry. Nonlinearly, the 95% CI for the 1.3-year amplitude did not overlap zero in 11 of the 12 BP and HR series. Given the usually strong synchronizing role of light and temperature, it is surprising that 5 of the 12 cardiovascular series had a numerically larger amplitude of the 1.3-year versus the precise 1.0-year component. The beating of the 61.3-year and 1.0-year components was shown by gliding spectra on actual and simulated data. Discussion and Conclusion: The shortest 5-year record (1998-2003) revealed an 61.3-year component closer to the solar wind speed period characterizing the entire available record (1994-2003) than the value for the concurrent 5-year span. Physiological variables may resonate with nonphotic environmental cycles that may have entered the genetic code during evolution.
