That said, anyone who survives long enough to get modern medical care wouldn't be killed in D&D terms, and in medieval times deaths caused by internal injuries could very well not be associated with the lightning bolts. After all, its not like they knew anything about them other than the fact that they were loud, bright, and destructive. Certainly not that they could cause enough damage to cause your internal organs to slowly fail over time without many (if any) visible symptoms.
