The 20,000 premature beats are not necessarily treated by surgery, but we should pay attention to find out the cause, and can be treated with oral antiarrhythmic drugs. The number of 20,000 premature beats is relatively high, and it is important to find out the causes of premature beats, such as myocardial ischemia, electrolyte disorders, severe hypoxia, etc. After removing the causes, the number of premature beats can be reduced. Oral antiarrhythmic drugs, such as propafenone and amiodarone, can also be taken to reduce the number of premature beats. Frequent premature beats may affect the function of the heart, and for patients for whom oral medications are not effective, radiofrequency ablation can be performed to reduce the number of premature beats. Some patients may not be able to tolerate antiarrhythmic medications and may also be candidates for surgical treatment. Patients with frequent premature beats should be careful to assess the severity of their condition and choose an appropriate treatment plan under the guidance of their physician.
