Just spent the last hour researching this one and my thtughos are consistent with Jason's. LQT-3 effectively treated by enhanced repolarization with a class 1B antiarrhythmic agent? Very curious too if she ever had true epilepsy or if the seizures were simply related to arrhythmia. Either way its good that she's doing well and not receiving shocks. Interesting case!
