Abstract

A sample of 3265 persons of both sexes aged 35-54 selected at random from six regions of Croatia was examined in 1969. In this paper changes in the electrocardiogram are analyzed according to occupation and sex. The subjects were divided in seven categories: farmers, unskilled workers, housewives, skilled workers, office workers, intellectuals, pensioners and others. There was no significant difference in the mean age among professions, with the exception of the group of pensioners which was older. ECG changes were analyzed as follows: myocardial infarction by Q wave, S-T segment depression, T wave inversion, atria-ventricular block of first degree, incomplete and complete right bundle branch block, left bundle branch block and often extrasystole. Q wave as a sign of myocardial infarction was seen in 0.6 per cent of persons regardless of profession. S-T segment depression and T wave inversion were higher in intellectuals and pensioners than in others, but differences were not statistically significant in men. In women S-T segment depression was higher in housewives and skilled workers, T wave inversion in pensioners and housewives (p < 0.05). The frequency of other ECG changes did not greatly differ among professions.
