| 中文摘要: |
| 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。 |
| 英文摘要: |
| Multiple atrioventricular node pathways are usually seen in clinical practice. Its esophageal electrophysiology has the
typical characteristics of tachycardia of multiple frequency. We found a case with trans-esophageal atrial pacing (TEAP) showed two
types of tachycardia. Following the successful improvement of the slow bypass at the right extension, the other slow bypass did not found
until 40 minutes later and it is ablated at left extension. It indicates that repeating intracardiac electrophysiology examination is critical for
atrioventricular node multi-paths and extending the observing time may be necessary. The goal is to ablate all the bypasses with one
operation. |
