This case report presents a rare and transient complication, during transseptal puncture for atrial fibrillation ablation. ST-segment elevation, hypotension and bradyarrhythmia related to catheterization were observed despite cineangiocoronariography without obstructive lesions. Clinical stability was achieved after administration of intravenous atropine and saline solution. It is speculated that the phenomenon is attributed to an increased vagal tone after the mechanical effect of transseptal puncture in the interatrial vagal network. The procedure was completed despite the phenomenon.</p>}, number={4}, journal={JOURNAL OF CARDIAC ARRHYTHMIAS}, author={Damasco do Vale, Paula and Teixeira Martins e Silva, Lívia and Macedo da Rocha, Jairo and Septimio Margalho, Carla and de Almeida Maia, Henrique César}, year={2020}, month={Nov.} }
