Paroxysmal atrial fibrillation (AF) can be cured with active treatment if it is not associated with organic heart disease, and does not affect the patient’s life expectancy. Paroxysmal atrial fibrillation has a high prevalence and is a relatively common arrhythmia. Paroxysmal atrial fibrillation can be seen in normal people, such as emotional excitement, drinking a lot of alcohol, etc., can cause paroxysmal atrial fibrillation. Organic causes of paroxysmal atrial fibrillation include hypertensive heart disease, rheumatic heart valve disease and mitral stenosis. Paroxysmal atrial fibrillation needs to maintain sinus rhythm as much as possible. Therefore, the treatment of paroxysmal atrial fibrillation, in addition to the use of anti-arrhythmic drugs such as amiodarone, can also use radiofrequency ablation, etc., after the treatment of paroxysmal atrial fibrillation can be controlled or even cured, and the impact on the patient’s life expectancy is not significant.
