A BOLT FROM THE BLUE - LIGHTNING STRIKE TO THE HEAD

We report an extraordinary event of a lightning strike to the head of a helmeted bicyclist that occurred under fair weather conditions with a cloudless sky, The patient sustained a cardiac arrest and hypoxic en cephalopathy with residual neurologic impairment, With the availabilit y of highly developed meteorologic equipment, we were able to determin e that the lightning ''bolt from the blue'' probably originated in a t hunderstorm that was about 16 km away and obscured by the mountains.
