Sometimes a thumping in the chest is usually considered to be caused by the occurrence of premature beats in the heart. Premature beats are heart beats caused by electrical impulses from abnormal pacing sites in the heart before the normal heartbeat occurs. Atrial or ventricular premature beats can be triggered when the body is in a state of long-term bad mood, irregular work and rest, bad habits, etc., resulting in occasional thumping in the chest, which will gradually disappear after removing the trigger. When the symptoms of thumping in the chest sometimes appear, it is recommended to avoid staying up late, keep enough sleep, avoid overwork, pay attention to rest, avoid anxiety and tension, and keep a relaxed and happy mood. If the symptoms persist, it is recommended to go to the hospital in time for targeted treatment.
