Aleteo auricular neonatal

atrial flutter is an uncommon arrhythmia in the newborn period; however, it must be considered in patients who have congestive heart failure with or without dilated cardiomyopathy (tachycardiomyopathy). neonatal atrial flutter has significant morbidity but an excellent long-term prognosis. the treatment options are diverse, with different rates of results in the centres′ reports, but virtually all infants will respond to direct current synchronized cardioversion. we describe a boy who developed the condition in the newborn period and whose diagnosis was established at 35 days of life. electrical cardioversion and amiodarone was performed with good evolution.
