Genetically-linked Na channelopathy
- Incomplete RBBB with ST elevation in V1-V3
- Increased risk of sudden cardiac death
  - ~10%/yr
- Much more common in men (up to 9x)

Type 1-Elevated ST segment (>2mm) descends w/ upward convexity to a TWI
Type 2-Elevated ST segment (>1mm) descends toward baseline then rises again (saddleback) to upright T wave
Type 3-Elevated ST segment (<1mm) descends toward baseline then rises again to upright T wave

-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 3-Elevated ST segment (<1mm) descends toward baseline then rises again to upright T wave
-*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.
