[1st experience on the use of an automatic ECG analysis in a large industrial plant in Erfurt]

By means of a device system consisting of constituents of the SW-production and own developmental works in the factory Kombinat VEB Umformtechnik (combinate nationally owned enterprise transformation technology) for the first time ECG serial examinations were performed with the help of the mechanical ECG-analysis. The corrected orthogonal system of Frank with 3 leads served as deviation system. The ECG-registration was independently performed by function nurses. 1,720 male and female workers of this factory at the age of 21 to 59 years served as test persons. The ECG-registration lasted 20 sec., the whole time of examination including the changing of clothes and the way from the working place to the examination room did not last more than 4 to 8 min. As diagnosis programme served that one developed by Pipberger. The mechanical analysis resulted in 74.4% in a normal course of the electrocardiographic current curve. Among the pathological or abnormal ECGs (25.6%) prevailed the vegetative-functional heart diseases with 92%. Then followed the chronic ischaemic heart diseases with 7.9% and the hypertension with 5.1%. Diseases of the heart and the blood circulation established for the first time referred to 8.9%. Of them 5% needed control and 3.9% needed therapy.
