A computer program for ECG analysis and interpretation developed at the University of Porto, Portugal is presented. The program runs on a microcomputer and employs the three-lead Frank VCG. The signals are sampled at 250 Hz with 8-bit precision during 5.5 s. Details on signal conditioning and wave recognition and measurement techniques are given. The diagnostic part of the program uses decision-tree logic. The decision rules are mainly derived from the Washington Code. The diagnostic accuracy of four classes (normal, left and right ventricular hypertrophies and myocardial infarction), evaluated in a sample of 1,075 pediatric and adult patients and classified by ECG-independent means was 76%. The program is currently being evaluated on the CSE database.
介绍了葡萄牙波尔图大学开发的一种用于心电图分析和解读的计算机程序。该程序在微型计算机上运行，并采用三导联Frank心向量图。信号在5.5秒内以250Hz的频率、8位精度进行采样。文中给出了信号调理以及波形识别和测量技术的详细信息。该程序的诊断部分使用决策树逻辑。决策规则主要源自华盛顿编码。在1075名儿科和成年患者样本中，通过与心电图无关的方法进行分类，对四类（正常、左心室肥厚、右心室肥厚和心肌梗死）的诊断准确率为76%。该程序目前正在CSE数据库上进行评估。
