Highlights that underlying sinus node dysfunction can be present in Brugada syndrome with atrial flutter, potentially requiring pacemaker insertion post-cardioversion.
Clinicians should monitor for bradycardia post-cardioversion in Brugada patients with flutter; case evidence leaves broader pacing indications open.
An incidentally diagnosed patient with Brugada syndrome was found to have atrial flutter on baseline electrocardiogram. He was DC (Direct current) cardioverted which revealed sick sinus syndrome. The patient was implanted with VVIR(Ventricular rate modulated pacing) pacemaker. Underlying sinus node dysfunction can be present in cases of Brugada syndrome with atrial flutter. The patient may require pacemaker insertion postcardioversion.
