Second-degree atrioventricular block in an adolescent with an acute alcohol intoxication.

Binge drinking adolescents often present to the emergency department with an alcohol intoxication. Known clinical signs of alcohol intoxications are impaired consciousness and vomiting, occasionally complicated by pulmonary aspiration. Emergency physicians are often not aware of the fact that excessive alcohol intake can also lead to atrioventricular (AV) conduction disturbances. We present a case of a second-degree AV block in an adolescent with an acute alcohol intoxication. The etiology of this condition is not well understood; possible explanations are reviewed in this manuscript.
