Abstract     The data of sudden cardiovascular mortality were collected between 1975 and 1983 in Brno (about 400 000 inhabitants). They include all cases of sudden decease due to cardiovascular defeat at home etc., not in the hospital (i.e., earlier than the medical assistance arrived). We have selected more than 30 different heliogeophysical and meteorological events and using the method of superposition of epoches the respective increase or decrease in mortality rates after the selected event has been studied. These increases or decreases have been tested to judge if they are significant or not. A significant increase follows after solar flares of imporantce 2 and 3, after the sudden commencement of geomagnetic storm, after the increase of air pressure and after the rapid change of relative humidity. A significant decrease has been observed after the day with very high activity of geomagnetic Pc1 pulsations. Finally, the data have been arranged with respect to lunar phase. A significant semilunar wave appears with maxima five days after new moon and after full moon. Its amplitude is comparable with the changes after the above mentioned effects. The courses of mortality rates in the days before and after the selected events are represented graphically.
