Abstract

The time structure (chronome) of mortality from cardiopathology in Tbilisi, Republic of Georgia, was assessed and examined for any influence by natural environmental factors, including geomagnetic activity. Monthly and daily mortality data, covering the span from January 1, 1980, to December 31, 1992, were analysed chronobiologically. In addition to an anticipated weekly variation and a prominent circannual variation, an about 10.5-year cycle was found to characterise cardiovascular mortality. The results were similar to those obtained for mortality from myocardial infarction in Minnesota from 1968 to 1996.
