The specific survival time of patients with atrial fibrillation is related to multiple factors such as the type of atrial fibrillation, the presence of comorbidities, and individual circumstances, and cannot be generalized. Atrial fibrillation is a common clinical arrhythmia that can also occur as a complication of many diseases. The symptoms of transient atrial fibrillation may also occur in cases of excessive alcohol abuse, strenuous exercise, late nights, and exertion, but without other discomfort, and are called isolated atrial fibrillation, which has no effect on the patient’s life expectancy. Also for patients with paroxysmal atrial fibrillation, their life expectancy will not be affected. However, for patients with persistent atrial fibrillation or permanent atrial fibrillation with underlying diseases such as coronary artery disease, myocardial infarction, hypertensive heart disease, rheumatic heart disease, etc., their life expectancy will be affected to some extent and they will easily develop into adverse cardiovascular events or even cause ventricular fibrillation, leading to loss of life. Patients are advised to go to the cardiology department of the hospital in time for discomfort, to clarify the type of atrial fibrillation and take active treatment.
