Sažetak
In a representative sarnple of 4210 men and women, aged 35-54 years, an electrocardiogram was recorded at rest and in 81.2% after exercise. The examination was lepeated after a period of three years. At both examinations significant Q waves were seen in 0.6 per cent, S-T segment depression in 4.8 per cent and inveited T wave in 8.5 per cent. Over the three year period the Q wave had disappeared in 17 per cent and S-T segment depression disappeared in 40 per cent. The most variable of these was the S-T segment depression of 0.5-0.9 mm. Inversion of T wave disappeared in 37 per cent. Q wave was twice as frequent in men than in women. Depression of the S-T segment and inversion of T vvave were two and a half times as frequent in women as in men. S-T segment depression of up to 0.5 mm at rest showed a deterioration in 39.6 per cent after exercise ; T wave inversion of 0-0.9 mm at rest deteriorated in 18.9 per cent.
