We report the first case of syncope with a documented asystole in a child triggered by hair grooming. No pathological findings were found, and a 15 s asystole event was recorded in an ambulatory 24 h electrocardiogram while her mother was combing her hair. Syncope by hair grooming is an infrequent type, reported in 162 patients. It is more prevalent in females (84.6% vs. 15.4%) with a mean age in the range of 8.9-12.3 years. The diagnostic is based on clinical history and the most frequent complementary examination is the electrocardiogram. No significant arrythmias or epileptic events have been reported.
