A normal person can have atrial premature contractions. If the number of atrial premature contractions is less than 100 on a 24-hour ECG, it does not require much treatment. If the number of premature atrial beats is greater than 100 and the patient has symptoms, further investigations should be performed to rule out other organic heart disease causing premature beats. If the number of premature atrial beats is more than 10,000 and the symptoms are typical, patients with duplex rhythm may choose to undergo radiofrequency ablation therapy to cure premature beats. In addition, the main medications for premature beats are betalactam and Chinese medicines such as heart pacifying granules and heart stabilizing granules.
