目的:探讨临床心电图无人区电轴,用于判别心房颤动伴宽QRS波群心电图特征及性质的临床意义。方法:分析95例心房颤动并宽QRS波群心电图。经常规12导联同步心电图或12导联同步动态心电图I、AVF导联目测心电轴,分析RR间期变化的范围、QRS波群形态及心室率等。结果:95例患者中心房颤动并心室内差异传导65例,心房颤动并室性期前收缩30例,其中13例房颤合并室性早搏心电轴位于无人区,17例室内差异传导中无1例心电轴位于无人区。结论:宽QRS波群无人区心电轴可作为判断心房颤动伴室性期前收缩的一个参考指标,特异性高,也可作为房颤合并室早或室内差传的诊断及鉴别诊断的一项指标。
Objective: To explore the clinical ECG unmanned axis, for the determination of atrial fibrillation with wide QRS complex electrocardiogram characteristics and clinical significance. Methods: 95 patients with atrial fibrillation and wide QRS complex ECG. Conventional 12-lead synchronous ECG or 12-lead synchronous dynamic electrocardiogram I, AVF lead visual ECG axis, the range of RR interval analysis, QRS complex and ventricular rate. Results: A total of 95 patients with central atrial fibrillation and ventricular differential transmission in 65 cases, atrial fibrillation and ventricular premature contractions in 30 cases, of which 13 cases of atrial fibrillation with ventricular premature beat in uninvolved ECG axis, 17 cases of differential conduction indoors No one case of ECG axis in no man’s land. Conclusion: The uncoased ECG axis of wide QRS complex can be used as a reference index to determine atrial fibrillation associated with premature ventricular contractions. It is of high specificity. It can also be used as a diagnostic and differential diagnosis for early or late onset of atrial fibrillation An indicator.
