1. The frequency of premature beats in a normal group of 606 men and 109 women, ranging between forty and fifty-nine years of age, was investigated. 2. The frequency of premature beats is much higher in the older group (fifty to fifty-nine years of age) than in the younger group (forty to fortynine years of age) in regard to the number of beats as well as number of subjects. The difference was statistically significant. 3. The incidence of premature ventricular beats is slightly higher than that of premature supraventricular ones. 4. In 78.8 per cent of the subjects with premature beats they occurred less than once in twenty heart beats; but in four of the thirty-three persons they occurred once or more in ten heart beats. 5. In view of the age trend, it is suggested that premature beats may be due to small ischemic areas in the myocardium.
