据最近30年来的研究,心向量图较为公认的价值是:(1)心向量的概念是解释心电图图形的理论基础;(2)对心肌梗塞的诊断比心电图敏感,定位比心电图准确,尤其是后壁和下壁及多部位的心肌梗塞;(3)对心室内传导阻滞的诊断比心电图明确; According to recent studies over the past 30 years, the more generally accepted value of cardiac vector diagrams is: (1) the concept of cardiac vector is the theoretical basis to explain electrocardiogram patterns; (2) the diagnosis of myocardial infarction is more sensitive than electrocardiogram and positioning is more accurate than electrocardiogram, especially Posterior wall and inferior wall and multi-site myocardial infarction; (3) the diagnosis of intraventricular conduction block than the ECG clear;
