A heart rate of 104 beats per minute is not normal in a quiet state, it is on the high side, but it is normal in an exercising state. 1. Heart rate refers to the number of heart beats per minute, the adult quiet heart rate range of 60-100 beats per minute, so if the heart rate of 104 beats / min is measured in a quiet state, compared with the normal quiet heart rate range belongs to the high level, reflecting the quiet state of the heart must be faster to meet the demand for the number of beats, indicating that the heart is in a poor functioning state. 2. If the patient’s heart rate reaches 104 beats per minute after exercise or under emotional excitement, it is a normal physiological situation and does not require special treatment, and can be normalized after rest and adjustment. 3. Pathologically fast heart rate may be caused by hyperthyroidism, anemia, arrhythmia, etc., which requires timely identification of the cause of the disease and symptomatic treatment. Therefore, to determine whether the heart rate value is normal or not, it depends on the state of the human body, not only from the value to judge.
