Atrial fibrillation does not usually heal on its own in normal people, but it can return to normal sinus rhythm after regular clinical treatment. Atrial fibrillation, short for atrial fibrillation, is a common arrhythmia. There are many causes of atrial fibrillation. In normal people, the symptoms of atrial fibrillation are more pronounced after certain triggers, such as heavy alcohol consumption, which stimulates the sympathetic nerves and makes them excited and the heart beat faster. And drinking alcohol tends to make blood vessels constrict, blood pressure rises, and the heart returns more or irregular blood flow, which will further aggravate the heart burden and lead to atrial fibrillation. In addition, rheumatic heart disease, cardiomyopathy, etc. are also causes of atrial fibrillation. If you are usually healthy and do not have cardiovascular disease, and you develop paroxysmal atrial fibrillation, you can return to sinus rhythm without drug intervention, but there is a possibility of recurrence. It is recommended to consult a cardiovascular physician after the occurrence of atrial fibrillation according to your own performance to clarify the cause. If it is paroxysmal atrial fibrillation, you can actively adjust your lifestyle, but you need to prevent recurrence; if it is pathological atrial fibrillation, you need to follow medical advice for treatment such as medication or radiofrequency ablation.
