摘要：The paper deals with the sudden cardiac death during training in male athletes in Croatia. The data are a part of a retrospective study dealing with 67 sudden death due to physical activity in men in Croatia during 25 years: from January 1, 1986 to December 31, 2010. Two of them suddenly died during training due to malignant ventricular arrhythmia because of the arrhythmogenic right ventricular dysplasia. First was a short trails runner aged 24, with no any previous physical discomforts, who suddenly collapsed and died during training. The second was a soccer player aged 13, with no any previous physical discomfort, who suddenly collapsed and died during training. A sudden cardiac death due to physical exercise in young athletes in Croatia suffered of arrhythmogenic right ventricular dysplasia reached 0.07/ 100.000 yearly (p=0.00000), in all young athletes suffered of heart diseases reached 0.19/100 000 (p=0.00005), and in the total male population aged 15–40 engaged in sports and recreational physical exercise: 0.71/100.0000 (p=0.00001).
