Pathophysiology
Genetically-linked sodium channelopathy, characterized by incomplete RBBB with ST elevation in V1 and V2, and an increased risk of sudden cardiac death
Note - EKG findings can be TRANSIENT
EKG Criteria
Type 1 - 2 mm J-point elevation a gradually descending ST segment and a negative T-wave Type 2 - saddle back pattern with at least 2 mm J-point elevation and at least 1 mm ST elevation with a positive or biphasic T-wave Type 3 - saddle back pattern with less than 2 mm J-point elevation and less than 1 mm ST elevation with a positive T-wave
Disposition
- a/w polymorphic v tach, v fib.
- mortality ~10% / yr
- pts need an AICD
