正常心脏的激动起源于窦房结,冲动以辐射状的方式先后激动右心房、房间隔及左心房,随之依次向下通过房室结、希氏束、束支及浦肯野纤维系统扩布到心室。如果起源于心室的激动逆行向上传导激动心房,则发生了室房逆传(Retrograde ventriculoatrial conduction,Retrograde VA conduction)现象。随着心电学及心电生理技术的发展,房室前传早已被广泛研究。1913年,Mines首次描述了室房逆传,此后心电学和心电生理学工作者对室房逆传的探索及研究已有一个世纪。室房逆传是房室折返性
Normal heart excitement originated in the sinus node, the impulse to a radial manner has excited the right atrium, atrial septal and left atrium, followed by down through the atrioventricular node, His bundle, bundle branch and Purkinje fiber system expansion Cloth to the ventricle. Retrograde ventriculoatrial conduction (Retrograde VA conduction) occurs if the anomalous origin of the ventricles retrograde upwards and induces the atria. With the development of ECG and electrophysiological techniques, atrioventricular prey has long been widely studied. In 1913, Mines first described the retrograde of the room, and since then there has been a century of exploration and research on retrograde chambers by cardiologists and cardiologists. Room backdoor is atrioventricular reentrant
