Heart rate 45. Is that normal?

Heart rate 45 beats/min is generally abnormal. The

normal heart rate of the human body is 60-100 beats/min, while the heart rate 45 beats/min is abnormal. It is a low state, which may be related to non-disease factors, such as the elderly, athletes, etc. The heart rate is slower than normal. But it may also be caused by disease factors, such as hypothyroidism, sinus node dysfunction, atrioventricular block, congenital heart disease, etc.

When the heart rate 45 beats/min occurs in the human body, it should also be combined with relevant examinations to clarify the cause, such as ECG examination, intracardiac electrophysiological examination, cardiac ultrasound examination, thyroid function examination, etc.
