A man in his early 20s presented with suspected syncope and shaking with no significant medical history. The patient fell asleep and his girlfriend tried to wake him, but he started shaking and slumped over on the ground. He denied confusion afterward but did not feel well with nausea, flushing, chest tightness, and a rapid heart rate. About 10 minutes later, he had a second syncopal episode for 2 to 3 minutes with more than 20 muscle jerks. On presentation at the emergency department, he was afebrile, blood pressure was 120/59 mm Hg, heart rate was 85 beats per min, respiratory rate was 16 breaths per min, and oxygen saturation was 96% on room air. His cardiac examination revealed normal heart sounds with no murmurs.
