To provide an in-depth interpretation of the spatial QRS-T contour, we established a set of vectorcardiographic parameters computed octant by octant. For each statement the criteria constitute a model which is closely related to pathophysiological patterns. The diagnostic strategy is of the heuristic type. For each diagnosis a table lists several criteria providing both specific and differential diagnostic information. Inter-table competition is handled by specific logic. The program classifies diagnoses according to the number of non-satisfied criteria. Three versions are available including 124, 51 and 7 diagnoses, respectively. The first, intended for interpretation of complex situations, has given satisfactory results in such situations. Rhythm analysis is performed from 8-second recordings. All functions--acquisition, quality control, choice of a dominant complex, wave recognition, parameter extraction, interpretation, editing, storage--are integrated into a mobile cart. A complementary program performs serial analysis of successive tracings. It highlights with great precision morphological changes in the spatial loops and interval variations.
为深入解读空间QRS-T轮廓，我们建立了一套逐卦限计算的向量心电图参数。对于每种诊断，其标准构成一个与病理生理模式密切相关的模型。诊断策略属于启发式类型。对于每种诊断，一个表格列出了几个标准，提供了特异性和鉴别诊断信息。表格间的竞争通过特定逻辑处理。该程序根据未满足标准的数量对诊断进行分类。有三个版本可供使用，分别包括124种、51种和7种诊断。第一个版本用于解读复杂情况，在这类情况下已取得了令人满意的结果。心律分析基于8秒的记录进行。所有功能——采集、质量控制、主导复合波选择、波形识别、参数提取、解读、编辑、存储——都集成在一辆移动推车上。一个补充程序对连续的心电图进行序列分析。它能非常精确地突出空间环路的形态变化和间期变化。
