摘要: Pulmonary veins electrical isolation as an invasive treatment of atrial fibrillation has been widely used in electrophysiology laboratories. This case report presents a rare and transient complication, during transseptal puncture for ablation. ST-segment elevation, hypotension bradyarrhythmia related to catheterization were observed despite cineangiocoronariography without obstructive lesions. Clinical stability was achieved after administration intravenous atropine saline solution. It is speculated that the phenomenon attributed increased vagal tone mechanical effect interatrial network. The procedure completed phenomenon.
