为鉴别横面 QRS 环向前向量增大的原因,本文选择223例心室前向力增大患者做心电向量图和心电图对比分析。资料与方法对我院3,000份心电向量图进行了整理分类,并均有常规心电图,其中223例心电向量图横面 QRS 环向前向量增大的患者,男213例,女10例,平均年龄49岁。应用上海 XX——2型心电向量图机,采用 Frank 体系,平卧位检查。结果223例患者心电向量图横面 QRS 环向前向量增大诊断标准均符合 Nakaya 等所订向前电力增大的心电向量图标准:1.横面 QRS 环最大向量角度在 In order to identify the reason why the QRS ring forward vector increases, we selected 223 cases of ventricular anterior force increase in patients with ECG vector diagram and ECG comparative analysis. Materials and Methods 3000 electrocardiogram maps of our hospital were sorted and classified. All of them had conventional electrocardiogram. Among them, 223 patients had 213 cases of QRS ring forward vector increasing, The average age is 49 years old. Application of Shanghai XX - 2 ECG vector chart machine, using the Frank system, supine position check. Results The diagnostic criteria of QRS ring forward vector increasing in 223 patients were in line with the standard of ECG vector diagram of forward power increase set by Nakaya et al .: 1. The maximum vector angle of transverse QRS ring was
