Respiratory cycle-dependent atrial tachycardia (RCAT) is rare. RCAT can be associated with severe symptoms and trigger atrial fibrillation. Focal radiofrequency ablation of RCAT can be a successful method of treatment. In the presented case RCAT originated from the roof of the left atrium - the site not previously reported in the literature. Ablation led to complete elimination of arrhythmia with no recurrence during follow up.
呼吸周期依赖性房性心动过速（RCAT）较为罕见。RCAT 可伴有严重症状并引发心房颤动。RCAT 的局灶性射频消融是一种成功的治疗方法。在本病例中，RCAT 起源于左心房顶部 - 该部位在以前的文献中尚未报道。消融导致心律失常完全消除，随访期间无复发。
