Premature beats are a pathology and are abnormal regardless of the number of beats in a day. Normal people should not have premature beats in a day, which means that the number of premature beats should be zero. However, for occasional premature beats that do not exceed 5 times or 500 times in 24 hours, such premature beats are occasional and do not require treatment. However, it does not mean that the episodic premature beats are normal, as long as the patient has premature beats, it is a pathological phenomenon. As long as the number of premature beats is relatively small and there is no organic heart disease, there is no need for treatment. Patients can go to the hospital to do dynamic electrocardiography to observe the overall number of premature beats in 24 hours, and if they find that the number of premature beats is not normal, they need to receive timely treatment.
