Manufacture and clinical application of XZY-1 model computer assisted ecg automatic diagnosis system

Summary

The manufacture and clinical application of XZY-1 model computer assisted ECG automatic diagnosis system and its hardware and software frames are described briefly in this paper. The results of 234 ECGs analysed by this system were as follows: (1) For the analysis of normal ECGs, the sensitivity, specificity and accuracy of this system were all over 95%. (2) For ventricular hypertrophy, bundle branch block and myocardial infarction, the sensitivity, specificity and accuracy were all over go%. (3) For the diagnosis of sinus arrhythmia, sinus bradycardia, sinus tachycardia, low voltage and clockwise and counterclockwise rotation, the sensitivity was over 80 %, while the specificity and accuracy were over 90 %.

The results of the preliminary study showed that this system is of help in analyzing ECGs without complicated arrhythmia. It might be useful for health survey in a large population because of its capacity for storing a large amount of information and high speed of processing.
