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

ABSTRACT:

Background

ST-segment deviation post-electrical cardioversion is a common finding amongst a significant number of patients. However, the mechanism by which this phenomenon occurs and its clinical implications are not fully understood.

Case summary

Four patients presented to our department with complaints of palpitations. They were found to have atrial fibrillation and were cardioverted using a synchronized direct current shock at 200 J. However, their telemetry immediately after the shock showed transiently an ST-segment elevation resembling Brugada Type 1 pattern. All telemetries normalized within 6 s from cardioversion.

Discussion

Through this report, we aim to raise mild concern about a possible safety issue related to synchronized electrical cardioversion with ele
