Circannual changes in ventricular function assessed by echocardiography.
Cardiac function may vary predictably along the 1-year scale. A circannual rhythm, more or less in phase is documented for 5 echocardiographic variables in clinically healthy Japanese adults.

Cross-spectral coherence between geomagnetic disturbance and human cardiovascular variables at non-societal frequencies.
A 35-year-old cardiologist monitored himself with an automatic ABPM-630 (Colin Electronics) monitor, mostly at 15-minute intervals around-the-clock for three years with a few interruptions. In this subject with a family history of high blood pressure and stroke, a cross-spectral analysis revealed a statistically significant coherence at 27.7 days between systolic and diastolic blood pressure and heart rate vs. the geomagnetic disturbance index, Kp. A lesser peak in coherence was found for systolic blood pressure with Kp at a trial period of 4.16 days (P = 0.046). These results suggest that changes in geomagnetism may influence the human circulation, at least in the presence of familial cardiovascular disease risk, and they may do so at frequencies that have no precise human-made cyclic worldwide match.
