The normal adult heart rate is between 60-100 beats per minute, and it is a normal physiological reaction for the heart rate to increase when walking. However, if the heart rate is greater than 100 beats/minute when walking, and the patient has symptoms of chest tightness and panic, the cause of the increased heart rate should be considered. The first step is to exclude whether there are heart problems, such as whether there is coronary heart disease, angina pectoris or other heart problems. Secondly, it is necessary to consider whether there is a disease of the thyroid system. If the patient’s heart rate increases while walking but is usually asymptomatic, it can be treated without treatment or special disposition, and regular observation is sufficient. Adult normal in walking, especially in walking flat road, heart rate between 80-100 beats / min, are normal physiological phenomenon.
