Developmental Research on Highly Accurate Computed Electrocardiograph

1.第一年的结果是将用BASIC语言开发的程序改写成C语言，对心电信号进行高速处理和分析。用于检查KARTIZER-2800版本4诊断准确性的患者数据保存在软盘中。随着波形诊断工作的完成，使用407例数据确定了诊断准确性。因此，它在所有项目中均超过99%。第二年（最后一年）的结果首先编写了一个程序，用于诊断心律失常的BASIC字，随后重写为C字。经628例分析，心律失常诊断的准确性与心电图基本一致.心电分析算法包括参数提取和诊断理论两部分。前者有许多问题，包括机械方面的问题，尚待解决。制造商的合作对于克服这些困难至关重要。特别是在分析心律失常时，没有它就不能获得很高的诊断率。今后，我们计划开发控制程序，并改进理论程序，以进一步提高准确性。

1. Results of the first year Rewriting work of the program developed by BASIC words into C words was carried out for high speed treatment and analysis of the electrocardiogram (ECG) signals. The data on the patients used for examination of the diagnostic accuracy of the version 4 of KARTIZER-2800 were saved in a floppy disk. As the work on the wave-pattern diagnosis was completed, the diagnostic accuracy was determined using 407 cases of the data. As a result, it exceeded 99% in all the item.2. Results of the second year(final year) A program was prepared first on BASIC words made for diagnosis of arrhythmia and subsequently rewritten into C words. After studying 628 cases the accuracy of the diagnosis of arrhythmia was almost simiar to that of wave.3. Reflection and future expansion of the research program Algorithm of ECG analysis consists of parameter extraction and diagnosis theory. Many proglems including mechanical ones remain to be solved in the former. Cooperation from the maker is essential for conquest of these difficulties. Especially, a high diagnostic rate can not be obtained in analysis of arrhythmia without it.In future, we are planning to develop the control program and to improve the theory program to rise the accuracy further.
