The National Institutes of Health defines apparent life-threatening event (ALTE) as an episode frightening to the observer and usually characterized by a combination of apnea, color change, change in muscle tone, choking, or gagging. An ALTE episode does not imply risk for sudden infant death syndrome. The incidence of ALTE is estimated to be 0.6 to 2.46 per 1,000 births. After medical evaluation, the cause of ALTE is never found in 50% of patients. Among the other 50%, GER, respiratory infection, and neurologic-related issues are the most common diagnosis found.
