Red Bull
reported on the death of a 21 year-old woman who died after drinking four cans of Red Bull as well as alcohol at "social levels". It was believed, but had not been proven, that she suffered from a rare heart condition called long QT Syndrome. She was on medication for epilepsy. A medical examination found that there were no illegal drugs in her system. The article quoted a doctor as saying, "The QT levels may have grown over a few years, or it may have been artificially pushed over the limit by caffeine".
