”Holiday heart syndrome is a syndrome characterized by arrhythmias in healthy individuals who consume excessive alcohol during the holidays. This syndrome is not related to a long history of heart disease, but is closely related to alcohol consumption. Alcohol and its metabolites can delay myocardial conduction time and lead to folding, as well as stimulate the release of norepinephrine from the myocardium, which can alter the myocardial nonstop period and lead to tachyarrhythmias, premature booting, paroxysmal tachycardia, atrial flutter, atrial fibrillation and other abnormal heart rhythms. How to diagnose “holiday heart syndrome”? 1. A history of continuous or repeated excessive alcohol consumption during the holiday season. 2. The patient has no previous history of heart disease and is mostly young and middle-aged. 3.Self-perceived palpitations, chest tightness, shortness of breath, atypical chest pain, dizziness or syncope. 4.Electrocardiogram examination: obvious signs of arrhythmia, especially frequent and multi-source premature beats and atrial fibrillation have important diagnostic value. 5.No abnormal myocardial enzymology examination, able to exclude acute myocardial infarction. 6, Elevated blood alcohol concentration. 7. Normal chest X-ray examination. How to prevent and treat “holiday heart syndrome”? Patients who have holiday syndrome must stop drinking, and must quit completely to prevent the recurrence of the condition from further deterioration. Healthy people should also try to drink less alcohol and consume less food that is high in sugar, salt and fat. 2.Intravenous infusion Discharge alcohol from the body in time to reduce the damaging effect on the heart. 3.Cardiac monitoring Give cardiac monitoring and necessary anti-arrhythmic drugs to the more serious patients. The disappearance of arrhythmia symptoms and the return of normal heartbeat rhythm and frequency suggest a good prognosis.
