简述了ＴＪ－Ⅲ型心电向量图微机自动分析诊断系统的构成和主要功能特征，报告了８８８例临床应用结果。同步记录２３例患者向量图进行人工目测和微机自动测算，１０项参数的测算结果基本一致。微机自动分析诊断７０３例正常成人向量图，与人工目测的诊断符合率为９６％，１４３例患者向量图的诊断符合率为９３％，总体诊断符合率９５．５％。该系统的整体性能、检测精度和速度较ＴＪ－Ⅱ型系统均有显著提高，分析指标和诊断有关心脏病种心室肥大有明显增多。
The composition and main functional characteristics of TJ-Ⅲ type electrocardiogram automatic diagnosis and diagnosis system are briefly described, and 888 clinical application results are reported. Simultaneous recording of vector images of 23 patients with manual visualization and computer automatic calculation, the results of 10 parameters are basically the same. Computer automatic analysis and diagnosis of 703 cases of normal adult vector chart, and manual visual diagnostic accuracy of 96%, 143 cases of patients with the diagnosis of vector chart was 93%, the overall diagnostic coincidence rate of 95.5%. The overall performance of the system, detection accuracy and speed than the TJ-Ⅱ type system were significantly improved, analysis of indicators and diagnosis of heart disease significantly increased ventricular hypertrophy.
