[Experience in the use of Smith's ECG evaluation program].
After the experiences with the use of the programme of Pipberger concerning the automatised ECG-analysis in clinic, outpatient department and factory public health, which were made at the Medical Academy Erfurt during the last years, at this time comparative examinations with the ECG-analysis programme of Smith were performed. The intake of data (3 orthogonal leads) is done by means of a data establishing unit developed by us. For the analog-digital-changing, the pretreatment of data and the transmission of the ECG-data on the digital magnet tape a process-calculator TPA-i is used. The analysis is performed by the computer Robotron 21. The evaluation of the results shows that, when a great number of patients is examined, normal curves are correctly estimated at 100%. The recognition rate of pathological curves has with 79.5% about the same size as the visual judgment. The deficiencies of the diagnostic programme of Smith must be essentially found in the relatively high proportion of falsely negative findings, the insufficient differentiation of the changes of the chamber variation, in the sometimes incorrect formation, why the classification of the curves in individual groups was performed. On account of the certain centage of falsely negative ones the programme is well recognition of normal findings and the tolerable pernotion of the diagnosis and the sometimes lacking insuited for screening examinations.
