In brief: Exclusion

All deaths are ultimately from the electrical system of the heart stopping, but if someone not on drugs simply falls over dead and the autopsy & labs show no clear fatal lesion, i look for entities that cause rhythm problems such as coronary atherosclerosis, emphysema, or structural defects.
When not present, look for a channelopathy (old ekg's, gene studies). That's a start -- wishing you comfort.
