目的观察电轴左偏对左前分支阻滞诊断的价值及临床意义。方法对240例心电图谱图形及心向量图形作回顾分析。结果电轴左偏是左前分支阻滞的诊断的重要指标。结论心电图与心向量相结合可明确诊断。心向量对左前分支阻滞的诊断优于心电图,对提高诊断准确率有指导意义。
Objective To observe the value and clinical significance of left axial deviation on the diagnosis of left anterior branch block. Methods Retrospective analysis of 240 cases ECG patterns and cardiac vector graphics. Results Left axial deviation is an important indicator of the diagnosis of left anterior branch block. Conclusions ECG combined with cardiac vector can confirm the diagnosis. The diagnosis of left anterior branch block by heart vector is better than electrocardiogram, which is instructive to improve the accuracy of diagnosis.
