The normal adult heart rate is between 60 and 100 beats per minute, and it is a normal physiological reaction to have a faster heart rate when walking. However, if the heart rate is greater than 100 beats/min when walking, and the patient has chest tightness and panic attacks, the cause of the increased heart rate should be considered. First of all, we should rule out any heart problems, such as coronary heart disease, angina pectoris or other heart problems. Next, consider whether the patient has a thyroid disorder. 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. In adults, a heart rate of 80-100 beats per minute is a normal physiological phenomenon when walking, especially when walking on flat roads.
