宽QRS波群心动过速的鉴别诊断一直是心律失常诊治的难点,无人区电轴是近几年在宽QRS波群心动过速的鉴别诊断中出现的一个新指标,对室性心动过速(室速)的特异性极高[1]。心房颤动(房颤)伴宽QRS波常见于房颤伴室性期前收缩、室速或房颤伴室内差异性传导及蝉联现象。由于两者在临床上治疗原则不同,所以两者的鉴别有重要的临床意义。12导
Wide QRS complex differential diagnosis of tachyarrhythmias has been the diagnosis and treatment of difficult, unmanned electric axis in recent years in the wide QRS complex tachycardia in the differential diagnosis of a new indicator of ventricular tachycardia Speed (VT) is extremely high [1]. Atrial fibrillation (atrial fibrillation) with a wide QRS wave is common in atrial fibrillation with premature ventricular contraction, ventricular tachycardia or atrial fibrillation with indoor differential conduction and reelection. Because of their different clinical treatment principles, the identification of the two has important clinical significance. 12 guides
