A 9-year-old boy who was enjoying a hot dog took a massive bite -- and went into cardiac arrest. But choking wasn't the cause, according to a study published Wednesday in the journal Pediatrics.
The terrifying incident had a much more unlikely cause, according to Dr. Isa Ozyilmaz. The chunk of frankfurter stimulated the boy's vagus nerve, and this triggered an abnormal heart rhythm that in turn caused his heart to abruptly stop beating, Ozyilmaz and his co-authors speculated in the case study. The nerve, which extends from the head to the abdomen, helps the heart and gastrointestinal system function. Overall the boy had a happy ending but did discover his rare condition called Brigade Syndrome.
