心房颤动(房颤)患者心电图出现宽QRS波常见于房颤伴差传或房颤伴室性期前收缩,二者的鉴别可为临床两种截然相反的治疗方案提供重要的依据。传统的鉴别方法诸如:前心动周期长的多为差传,初始向量与其他室上性下传者相同者多为差传、呈右束支阻滞图形者多为差传、宽QRS形态不一致
Atrial fibrillation (ECG) patients with wide QRS complex electrocardiogram is common in patients with atrial fibrillation with atrial fibrillation or ventricular premature contractions, the identification of the two clinical clinics can provide an important basis for the opposite treatment. Traditional methods of identification such as: long before the heart cycle is mostly spread, the initial vector and other types of supratentorial descendants are mostly differential biography, showed the right bundle branch block graphics are mostly spread, wide QRS morphology inconsistent
