Summary

Higher geomagnetic activity (GMA) is linked to fewer cardiac arrhythmias and sudden cardiac death (SCD) events. This suggests GMA may offer a protective effect against life-threatening cardiac events.

Area of Science:

  • Clinical Cosmobiology
  • Environmental Cardiology

Background:

  • Investigates the relationship between environmental factors and cardiac health.
  • Focuses on geomagnetic activity (GMA), cosmic rays, and proton flux in relation to cardiac arrhythmias and sudden cardiac death (SCD).

Purpose of the Study:

  • To review studies linking environmental physical activity factors to life-threatening cardiac arrhythmias and SCD.
  • To explore the role of geomagnetic activity (GMA) and cosmic radiation in cardiovascular events.

Main Methods:

  • Compared daily and monthly distributions of cardiac arrhythmias and SCD with levels of GMA, space proton flux, and cosmic ray activity (neutron counts).
  • Utilized cosmophysical data from international space science institutions.

Main Results:

  • Identified an inverse relationship between the frequency of cardiac arrhythmic events/SCD and the level of daily GMA.
  • Found that higher GMA levels correlate with a lower incidence of cardiac events.

Conclusions:

  • Presumes a protective effect of GMA on cardiac arrhythmias and SCD.
  • Ongoing research is examining the influence of cosmic ray activity on the natural history of these cardiac events.
