Key result
Holiday Heart Syndrome, characterized by alcohol-induced atrial fibrillation, spontaneously resolves in over 90% of cases but recurs in 20-30% of patients within 12 months.
Holiday Heart Syndrome is an alcohol-induced atrial arrhythmia that typically resolves spontaneously but has a 20-30% recurrence rate within 12 months.
Alerts clinicians to alcohol-triggered arrhythmias; novel level 5 finding leaves mechanisms and management open.
Holiday Heart Syndrome, also known as alcohol-induced atrial arrhythmia, is a syndrome characterized by the occurrence of irregular heartbeats caused by alcohol consumption. It was first described at the end of the seventies of the last century by Philip Ettinker. The effects of alcohol on arrhythmogenicity are associated with the occurrence of reentry atrial and ventricular arrhythmias with different and incompletely explained mechanisms. The most common clinical symptom is palpitations after consuming an excessive amount of alcohol, but other symptoms and signs may also appear, such as: syncope, dyspnea, angina pectoris, etc. Differential diagnosis includes: alcohol intoxication, acute coronary syndrome, alcoholic and dilated cardiomyopathy, pulmonary thromboembolism, pneumonia, and other arrhythmias. If anticoagulation therapy is required, it is reasonable to use CHA 2 DS 2 VASc and HAS-B scores. The prognosis depends on the presence of heart disease. In most cases (> 90%) of atrial fibrillation caused by alcohol, the disorder spontaneously stops, and about 20-30% recurs within 12 months.

Serafimov et al. (2024) conducted a review in Holiday Heart Syndrome (alcohol-induced atrial fibrillation). Alcohol consumption was evaluated. Holiday Heart Syndrome, characterized by alcohol-induced atrial fibrillation, spontaneously resolves in over 90% of cases but recurs in 20-30% of patients within 12 months.
