摘　　要：目的探讨逸搏心律伴室房双径路传导心电图特征和发生机制。方法选取11例逸搏心律伴室房双径路传导患者的心电图资料进行回顾性分析。结果 11例逸搏心律包括交界性7例、室性4例,逸搏频率相对匀齐,其后跟随P波,P波呈两种形态的7例,单一形态的4例。均存在长、短两种R-P间期,差值明显大于0.06s,长、短RP间期最大增量变化在0.11~0.38s(平均0.23±0.09s),3例伴随单个心室回波,1例出现房室结折返性心动过速。结论室房双径路传导是一种少见的心电现象,通过体表心电图合理分析,可以对逆向型双径路做出初步诊断,为下一步实施电生理检查和治疗提供指导依据。Objective To investigate escape rhythm with dual pathways ventriculoatrial conduction （VAC） and its electrocardiogram（ECG） characteristics and mechanisms. Methods To select 11 cases of escape rhythm with dual VAC, and to analyze their ECG data retrospectively. Results In 11 patients with escape rhythm, 7 patients were junctional and 4 patients were ventricular.The frequency of the escape rhythm was relatively regular,and followed by retrograde P wave, in which 7 cases showed two kinds of forms ,and 4 cases showed only one kind. There were long and short R-P interval with obvious difference （〉0.06s）, the biggest increment chang in the scope of 0.11~0.38s （average 0.23 ± 0.09s）. 3 cases accompanied by single ventricular echo beat,1 case come up with atrioventricular nodal reentrant tachycardia. Conclusions Dual VAC was a kind of uncommon ECG phenomena. By means of analyzing surface EGG reasonably, we can make a primary diagnosis to retrograde dual pathways and provide evidence of guide for further elec^ophysiological examination.
