背景-在右心房和左心房的波前之间的相互作用可能是重要的维护心房fibrillation.Methods和Results-Eighteen患者（年龄44+/-12岁）没有结构性心脏病起搏期间从远端冠状窦（CS）或后左心房进行右心房电解剖标测的电生理特性和优先途径知之甚少。在CS远端起搏过程中，9例患者在CS口附近显示出单次经中隔突破，1例患者在假定的Bachmann束插入附近的高位右心房中，1例患者在卵圆窝附近。从刺激到CS os的平均激活时间为48 ± 15 ms，而到Bachmann束插入的平均激活时间为86 ± 15 ms（P
Background-Interaction between wave fronts in the right and left atrium may be important for maintenance of atrial fibrillation, but little is known about electrophysiological properties and preferential routes of transseptal conduction.Methods and Results-Eighteen patients (age 44+/-12 years) without structural heart disease underwent right atrial electroanatomic mapping during pacing from the distal coronary sinus (CS) or the posterior left atrium. During distal CS pacing, 9 patients demonstrated a single transseptal breakthrough near the CS os, 1 patient in the high right atrium near the presumed insertion of Bachmann's bundle and 1 patient near the fossa ovalis. The mean activation time from stimulus to CS os was 48+/-15 ms compared with 86+/-15 ms to Bachmann's bundle insertion (P
