Heart rate's 125. Is that normal?

Heart rate 125 beats/min is normal, usually combined with the actual situation analysis.

If the patient before the measurement of heart rate there is strenuous exercise, mood swings, drinking coffee or strong tea, eating a lot of spicy stimulating food, etc., easy to stimulate sympathetic nerves, causing sympathetic nerves in a highly excited state, enhance cardiac contractility, resulting in heart rate rise, this time is generally normal phenomenon. If the patient measures the heart rate in a calm state, the above conditions do not exist before the measurement, which will not cause sympathetic excitation and will not affect the normal beating of the heart. At this time, it is usually abnormal. It may be caused by myocardial ischemia causing large-scale necrosis of myocardial cells, affecting the blood circulation of the heart and causing the heart to beat too fast.
