The survival time of atrial fibrillation depends on the severity of the condition and is dependent on the actual situation, with significant individual variability. In general, for patients with stable atrial fibrillation, the normal life expectancy is usually not affected. However, for patients with atrial fibrillation who have serious conditions, strokes, heart failure and other complications, and whose conditions are unstable, it is easy to affect the normal life expectancy to a certain extent, and their lives may be at risk at any time, so it is impossible to conclude what the normal life expectancy is.
