Seasonal variations in myocardial infarctions and the possible biotropic influence of short-period geomagnetic pulsations on the human cardiovascular system

摘要: Analysis of ambulance calls in Moscow during 1979–1981 reporting myocardial infarction (85 700 events), sudden death (71 and hypertension crises (165 500 events) shows the presence clear seasonal variations with a deep summer minimum winter maximum. The same trend was upon analysis monthly data on mortality Bulgaria over 15 years (1970–1985). One biotropic factors influencing human cardiovascular system can be geomagnetic pulsations Pc1, agreeing frequency cardiac rhythms. In trend, Pc1 have maximum intensity winter. comparison observation catalog revealed that, ∼70% days, an abnormally large number accompanied by Pc1; their concurrence half again chance expectation. Besides, it determined that influence magnetic storms much higher than summer. plausible reasons could production pineal hormone melatonin, which destabilized organism increased its sensitivity to disturbances attended Pc1.
