Title: Exercise induced Brugada Type I pattern of ECG in a asymptomatic adult male
Brugada syndrome is a rare inherited channelopathy leading to ventricular fibrillation & sudden cardiac death in structurally normal hearts.
It is well known that brugada pattern is unmasked by sodium channel blocking agents like ajmaline,flecainide, procainamide and enhanced vagal tone( 1). Adrenargic stimulation with exercise and isoprenaline decreases the elevation of ST segment (2). Here with we present a ECG image of a patient who developed type I Brugada ECG pattern ( RBBB,ST elevation with T inversion in V1) during routine stress test which is done for annual health check up. Only few case reports are available which showed exercise induced type I Brugada pattern( 3). RBBB during exercise can occur rarely as a benign finding in which ST depression is seen V1 and V2.RBBB can be rarely due to ischemia during exercise and it is characterized by Q RBBB with ST elevation in V1,V2 and ST depression in V5,V6.In our patient RBBB with ST elevation in V1 is seen with no ST depression in V5,V6.
