A large international co-operative project, sponsored by the European Commission, was launched in 1980 aimed at developing common standards for quantitative electrocardiography. The first and main objective of the project was to reduce the wide variation in wave measurements currently obtained by electrocardiographic computer programs. To this end a reference library was developed and a comprehensive reviewing scheme was devised for the visual determination of the onsets and offsets of P, QRS and T. This task was performed by a board of cardiologists on highly amplified recordings, in an interactive four round Delphi-type analysis. The reference library, so obtained, has become an internationally recognized yardstick for the evaluation and improvement of ECG measurement programs. It has been used to test the performance of 9 VCG and 10 standard 12-lead programs. The library proved to be a useful instrument in the establishment of recommendations for more precise measurement rules and definitions. Records with added noise and multi-lead ECGs were subsequently analysed to meet specific objectives. The project was expanded in 1984 towards testing and improvement of diagnostic criteria and classification programs.
一项由欧盟委员会资助的大型国际合作项目于1980年启动，旨在制定心电图定量分析的通用标准。该项目的首要目标是减少目前心电图计算机程序在波形测量方面存在的巨大差异。为此，建立了一个参考库，并设计了一个全面的审核方案，用于直观确定P、QRS和T波的起始点和终点。这项任务由一个心脏病专家委员会在高放大倍数记录上，通过交互式的四轮德尔菲式分析来完成。由此获得的参考库已成为评估和改进心电图测量程序的国际公认标准。它已被用于测试9种向量心电图和10种标准12导联程序的性能。该库被证明是制定更精确测量规则和定义建议的有用工具。随后对添加了噪声的记录和多导联心电图进行了分析，以实现特定目标。1984年，该项目扩展到诊断标准和分类程序的测试与改进。
