Panic attack

According to Matteusz, a panic attack felt like death but wasn't. Charlie Smith had a panic attack when he found himself trapped in Class B3 in no-time, no-space, due to his claustrophobia. Charlie thought he was dying. It made his heart beat twice as fast as normal. April MacLean acknowledged that he might have a heart attack if they remained there. (TV: Detained)
