A heart rate of 102 beats/minute while walking is generally normal. Under normal circumstances, the range of heart rate is 60-100 beats per minute, which refers to the heart rate in a quiet state. When a person is exercising, the heart rate can increase, so a heart rate of 102 beats/minute while walking is normal. If the patient’s heart rate increases too much after exercise, and symptoms such as chest tightness, dyspnea, and dizziness occur, the patient needs to stop exercising and rest in place. If the symptoms do not improve after a period of rest, it is considered to be accompanied by cardiovascular disease, then it is necessary to consult a doctor immediately. In addition, it is recommended that patients who feel unwell go to a regular hospital in a timely manner and follow the doctor’s instructions for treatment to avoid delaying their condition.
