Past medical history
The patient had a history of arterial hypertension, dyslipidemia and sleep apnea-hypoapnea syndrome (SAHS) in treatment with CPAP. Paroxysmal AF was diagnosticated five years ago undergoing electrical cardioversion with premature recurrence. Dronedarone was initially used as an antiarrhythmic drug, but after the recurrence of AF was changed to amiodarone. Echocardiography showed left atrial enlargement with preserved left ventricular function without valvulopathies.
Despite the treatment with amiodarone the patient persisted in AF so a new electrical cardioversion was programmed followed by pulmonary vein isolation.
