Abstract:
A 55-year-old woman was referred for recurrent palpitations. A 48-hour ambulatory cardiac monitor revealed an atrial tachycardia rate up to 170 beats per minute. A subsequent electrophysiology study revealed atrial fibrillation and both typical and atypical atrial flutter. Computed tomography revealed multiple pulmonary nodules, and an endobronchial ultrasound-guided fine-needle aspiration confirmed the diagnosis of pulmonary sarcoidosis. The patient underwent radiofrequency ablation of the cavotricuspid isthmus and left common, right superior, and right inferior pulmonary vein isolation via cryoablation, without recurrent symptoms.
