We evaluated the patterns of interruption of atrial flutter (AFl) induced by rapid atrial pacing in 10 patients using standard electrophysiologic techniques. We observed 3 patterns of interruption of AFl: 1) interruption resulting from block of an orthodromic wavefront within the reentry loop in 5 patients; 2) interruption when pacing impulses no longer captured all of the recording sites in the atrium during rapid atrial pacing in 2 patients, and 3) interruption with 1 echo wave after the cessation of pacing in 3 patients. These findings suggest that there are patterns of interruption of AFl other than that resulting from a simple block of an orthodromic wavefront within the reentry loop.
我们使用标准电生理技术评估了10例患者在快速心房起搏诱导下的心房扑动（AFl）中断模式。我们观察到3种AFl中断模式：1）5例患者中，折返环内顺行波前阻滞导致的中断；2）2例患者在快速心房起搏期间，起搏冲动不再夺获心房内所有记录部位时发生的中断；3）3例患者在起搏停止后出现1个回声波时的中断。这些发现提示，除了折返环内顺行波前简单阻滞导致的中断外，还存在其他AFl中断模式。
