ABSTRACT: Atrial fibrillation is a cardiac arrhythmia of high prevalence in the population, especially in the elderly. Its main electrical characteristics are the interval between two successive irregular R waves, absence of P waves and presence of f waves between QRS complexes. The most common symptoms of atrial fibrillation are irregular palpitations associated with dyspnea, dizziness, feeling tired, fatigue and general malaise, but not all patients have any symptoms. The present report presents the history of an elderly patient who arrived at the hospital’s emergency department with irregular heart rhythm and palpitations. The patient’s symptoms, associated with the electrocardiogram results, indicated paroxysmal atrial fibrillation. Electrical cardioversion was performed, and after, cardiac ablation via the femoral vein at the hospital’s cardiology service. There were no complications during the procedure. As a routine imaging exam after ablation, control esophagogastroduodenoscopy was requested to verify that there was no formation of atrio-esophageal fistula developed by the invasive ablation procedure and electrocardiogram, which showed normal sinus rhythm. The patient remained in the cardiac intensive care unit for observation for 24 hours. After the electrical cardioversion and catheter ablation procedures, the patient improved his clinical picture of atrial fibrillation and was discharged after 24 hours of hospitalization. He received treatment to perform at home, to reduce acid reflux into the esophagus and to prevent thrombosis. He did not present pulmonary thromboembolism after hospital discharge. It is believed, therefore, that this form of treatment and management of paroxysmal atrial fibrillation is effective for the solution of the proposed problem and can also serve as a reference for other professionals within the cardiology service.
