A well-informed bystander and an astute physician can make the difference between an outcome of death or lifelong disability versus complete or near-complete recovery. What is done in the first few minutes after such an event is the predominant predictor of success.

The discussion that follows the case centers on the pathophysiology of being struck by lightning and on issues unique to being struck in a stadium full of people.
