130 healthy persons and 146 cardiac patients with left ventricular cardiac overload were examined by 4 electrophysiologic methods: corrected orthogonal electrocardiogram according to Frank, corrected orthogonal vectorcardiogram, space electrocardiogram, high-speed space electrocardiogram. 76 indices were examined. The cardiac patients were classified into two basic groups: patients with systolic overload and patients with diastolic overload. By variational analysis, performed in all patients, statistically significant differences were found between the cardiac patients and the healthy persons. On the basis of the criteria sensitivity, specificity and assessment of realization the best indices for every method were determined. In order to improve the sensitivity "sets" with sensitivity of 91-96% are established by mathematical calculations. The "sets" are made up of 4 indices from different methods and are suitable for inclusion in computer programs.
采用4种电生理方法对130名健康人和146名左心室心脏负荷过重的心脏病患者进行了检查：根据Frank法校正的正交心电图、校正的正交向量心电图、空间心电图、高速空间心电图。检查了76项指标。心脏病患者分为两个基本组：收缩期负荷过重患者和舒张期负荷过重患者。通过对所有患者进行的方差分析，发现心脏病患者与健康人之间存在统计学上的显著差异。根据标准敏感性、特异性和实现评估，确定了每种方法的最佳指标。为了提高敏感性，通过数学计算建立了敏感性为91%至96%的“指标组合”。“指标组合”由来自不同方法的4项指标组成，适用于纳入计算机程序。
