Poor digestion can cause premature beats. Abnormal heart structure and function are common causes, such as those with underlying cardiovascular diseases, which are more likely to cause premature beats, and external stimuli, such as emotional stress and anxiety, can also cause premature beats. The consumption of excitatory foods such as coffee and tea, as well as poor digestion can affect eating habits and emotional changes, which can indirectly lead to premature beats. Premature beats are not a terrible disease. It is recommended to check ECG or 24-hour ambulatory ECG, and if the beats are not frequent, they will improve by adjusting to reduce external stimulation. People with poor digestion need to eat regularly, choose easily digestible food, reduce the burden on the stomach and intestines, and maintain a relaxed mood.
