Atrial fibrillation is a common arrhythmia among many middle-aged and elderly people, and in our country, which has a strong culture of alcohol consumption, many people enjoy drinking. So, can you drink alcohol if you have atrial fibrillation? My advice is that it's best not to drink. Modern medical research has shown that alcohol can potentially trigger attacks of atrial fibrillation, and in our clinical practice, we often find that many patients experience an onset of atrial fibrillation by drinking alcohol, sometimes even necessitating hospital treatment due to the episodes. Therefore, it is recommended that patients with atrial fibrillation avoid or minimize alcohol consumption.
