Pulse is 55. Is it normal?

If the pulse is 55 beats/min, it is somewhat low. Because the normal pulse is the same as the heart rate. If it is normal, it is 60-100 beats per minute. At present, there are some low cases. You can check the ECG. If the sinus rhythm is 55 beats, it means that there is bradycardia. You need to use some symptomatic medication. If it is due to weak qi and blood, frequent poor diet or some chronic diarrhea. There are also some cases of heart and blood deficiency, some physical conditions such as sweating easily when slightly active or eating, and some malnutrition problems. You need to see traditional Chinese medicine and then give symptomatic treatment to replenish qi and blood.
