Atrial premature beats and ventricular premature beats are very common types of arrhythmia in our daily life. Generally, most atrial premature beats and ventricular premature beats are not serious, do not involve organic heart disease, and usually do not cause symptoms. The occurrence of these atrial and ventricular premature beats is often related to factors such as staying up late, fatigue, anxiety, drinking strong tea, or coffee. If the cardiac ultrasound and blood tests for thyroid function are normal, then these premature beats are not serious and will not affect health. Generally, no special treatment is needed and there is no need for concern.
