Abstract

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.
