Frequent premature atrial contractions have no underlying cause. Frequent premature atrial contractions can be seen in normal people or in diseases such as hyperthyroidism, pulmonary heart disease, hypertensive heart disease, coronary heart disease, etc. The treatment plan is as follows: 1) if there is underlying disease, treat the underlying disease; 2) if the symptoms are not obvious, there is no need for medication; 3) if the symptoms are obvious, consider using anti-arrhythmic drugs, such as beta-blockers, and pay attention to whether there are other emotional causes, such as mental tension, work stress, poor sleep, poor rest, etc. If you have these conditions, you should try to improve them. Frequent premature atrial contractions mainly depend on the presence of organic heart disease, and if so, the most appropriate treatment is to target the primary cause. If there are no symptoms, you can consider using anti-arrhythmic drugs, and at the same time, pay attention to whether there are other triggers, and removing the triggers is also an important aspect.
