摘要

最近的报道强调了窦性心律中功能底物映射的作用，以预测左房性心动过速（AT）的临界峡部。在这篇文章中，我们报告了一例63岁的女性患者在肺静脉隔离后因复发性AT入院。虽然窦性心律显示左心房电压正常，但程序性外刺激显示前壁局部电图诱发电位随时间延长而降低。在功能底物映射过程中，AT的临界峡与减速区共定位。射频消融成功终止AT。

Functional Substrate Mapping Using Atrial Decrement Evoked Potentials to Predict Critical Isthmus of Atrial Tachycardia.

Recent reports highlighted the role of functional substrate mapping during sinus rhythm to predict the critical isthmus of left atrial tachycardias (AT). In this article, we reported a case of a 63-year-old female patient who was admitted with recurrent AT after pulmonary vein isolation. Although sinus rhythm revealed normal left atrium voltages, programmed stimulation with extrastimulus revealed decrement evoked potentials with prolongation in local electrograms on the anterior wall. Critical isthmus of AT was colocalized with deceleration zones during functional substrate mapping. Radiofrequency ablation successfully terminated AT.
