Arrhythmia is arrhythmia, which has a wide range. If you feel abnormal pulse activity, you should immediately go to the clinic to do an electrocardiogram to confirm what type of arrhythmia it is. Arrhythmia (premature beats, atrial fibrillation, bradycardia, etc.). ) may cause stomach discomfort, but stomach discomfort (satiety) may also cause arrhythmia. Only after your arrhythmia is diagnosed can you decide how to treat it.
