房室结多径路在临床中常见,其食道电生理有较典型特征,如多种频率心动过速。我们发现一例食道调搏存在两种频率心动过速患者,第一次在右延伸处成功慢径改良后较长时间不能发现另一条慢径存在,40分钟后另一条慢径才表现并于左延长处成功消融。提示如食道电生理发现存在多径路时心内电生理一定要多次重复检查,必要时延长观察时间,力争一次完整消融多条径路。
Atrioventricular node pathways common in clinical practice, the esophageal electrophysiology has more typical features, such as a variety of frequency tachycardia. We found a case of esophageal pacing in patients with two kinds of frequency tachycardia, the first time in the right extension after the successful improvement of the slow pathway can not find another slow path exists, 40 minutes after the other slow path only in the performance of the left Extension of the successful ablation. Tips If the esophageal electrophysiological findings exist multi-pathological electrophysiology must repeatedly check, if necessary, extend the observation time, and strive to completely ablate a number of trails.
