Holiday Heart Syndrome




Holiday Heart Syndrome (HHS) describes the occurrence of an acute cardiac arrhythmia after an episode of acute alcohol excess or alcohol withdrawal. The condition may also occur in predisposed individuals that consume a small amount of alcohol. The name of the condition stems from the fact that episodes were initially observed more frequently around weekends and public holidays. The most commonly seen arryhthmia is atrial fibrillation, which usually converts to normal sinus rhythm within 24 hours.
