Heart rate's over 90. Close to 100. Is that normal?

Heart rate of more than 90 beats per minute is usually normal.

Adults in quiet, awake state normal heart rate range is 60-100 beats per minute, heart rate of more than 90 beats per minute nearly 100 does not exceed the normal range, so it is normal. Daily life can observe their own heart rate, if the heart rate exceeds 100 beats per minute, may be related to physical factors such as strenuous exercise, emotional excitement, may also be caused by infection, severe anemia, hyperthyroidism and other diseases. If the heart rate is lower than 60 beats/min, it may be related to factors such as long-term exercise, hypothyroidism, sinus node dysfunction, etc.

For patients with abnormal heart rate, it should be combined with other examinations to determine the cause, such as physical examination, thyroid hormone examination, ECG examination, etc., and follow the doctor's advice to treat the cause.
