Whether a woman’s heart rate of 99 beats/min is normal depends on the specific situation, whether it is in a quiet state or in an exercise state, and whether there are uncomfortable symptoms. The normal adult heart rate in the quiet state is 60-100 beats/min, and the ideal heart rate in the quiet state is about 70 beats/min. The heart rate of 99 beats/min in women in the quiet state is in the normal range, but not in the range of the ideal heart rate. If the heart rate of 99 beats/min in a quiet state is accompanied by chest tightness and panic, it is not normal and is considered to be caused by diseases, such as hyperthyroidism and myocarditis. When the human body exercises most of the heart rate will increase, the appropriate exercise heart rate = 170 – age, 30-year-old adults exercise heart rate control in no more than 140 times / minute is appropriate, in the exercise state heart rate of 99 times / minute is normal.
