Transient appearance of Brugada-like Type 1 electrocardiogram pattern immediately after biphasic synchronized electrical cardioversion for atrial fibrillation: a case series.

Through this report, we aim to raise mild concern about a possible safety issue related to synchronized electrical cardioversion with electrodes positioned in an anteroposterior fashion. Also, we try to give a pathophysiological explanation to this finding on the base of the knowledge accumulated through the years on Brugada syndrome.
