The main features of Caceres-USPHS (version HP-3) program for automatic analysis of the ECG are reviewed. Our experience at the Ospedale Regionale di Udine has now reached a total of 40,000 tracings analyzed by such a program and with an HP 1530-A computer system. In a detailed study of 1,000 consecutive computer-analyzed tracings reviewed by three experienced cardiologists, 534 were normal and 466 abnormal. A high degree of specificity was detected in the normal group (only 1.5% of false negatives) while the sensivity was rather low. In the abnormal group there were 18.1% of false positives and while the agreement was 100% in complete bundle branch block and some types of infarction, it was 56% in atrial fibrillation and 47% in incomplete right bundle branch block. Program errors were more common in measurements and pattern recognition; they were unusual in the program logic (0.3%). A significant improvement over comparable data obtained one year previously was attributed to a better quality control in data recording and to increase physician acceptance of the program diagnostic criteria. On the current and past figures of accuracy, it is concluded that the version HP-3 of Caceres-USPHS program represents a step forward in computer-derived ECG interpretation. However more progress is still needed for a larger and more profitable clinical application of this ECG computer program.
本文回顾了用于心电图自动分析的卡塞雷斯-美国公共卫生署（版本HP-3）程序的主要特点。我们在乌迪内地区医院的经验表明，使用该程序和惠普1530-A计算机系统现已总共分析了40000份心电图。在一项由三位经验丰富的心脏病专家对1000份连续计算机分析心电图进行的详细研究中，534份正常，466份异常。正常组检测到高度特异性（假阴性仅1.5%），而敏感性较低。异常组中有18.1%的假阳性，完全性束支传导阻滞和某些类型的梗死的一致性为100%，房颤为56%，不完全性右束支传导阻滞为47%。程序错误在测量和模式识别中更为常见；在程序逻辑中则不常见（0.3%）。与一年前获得的可比数据相比有显著改善，这归因于数据记录中更好的质量控制以及医生对程序诊断标准接受度的提高。根据当前和过去的准确性数据得出结论，卡塞雷斯-美国公共卫生署程序的HP-3版本代表了计算机辅助心电图解读的一个进步。然而，要使该心电图计算机程序在更大范围和更有成效的临床应用中取得更多进展，仍需努力。
