Heart rate's 90. Is that normal?

Heart rate refers to the frequency of heart beats per minute. A heart rate of 90 beats per minute is a normal range.

An adult's normal heart rate range at rest is between 60-100 beats per minute, so 90 beats per minute is normal. If the heart rate is too fast or too slow, it is abnormal. The ideal heart rate for adults should not exceed 70 beats per minute, so it is normal for the heart rate to reach 90 beats per minute, but it is not recommended to maintain it for a long time.

The heart rate measured at 90 beats per minute may be caused by intense exercise, alcoholism or drinking strong tea, coffee, etc. It may also be caused by severe anemia, hyperthyroidism, electrolyte disorders and other disease factors. It is recommended that patients identify the cause as soon as possible and carry out targeted treatment.
