Whether the heart rate reaches 170 beats/min after running is harmful to the body needs to be judged in the light of one’s own situation.
1. Running and other sports can cause an increase in heart rate, but generally will not reach 170 beats/min. But in the case of too intense exercise, the heart rate can reach 170 times / min, if the heart rate reaches 170 times / min, and there is no panic, chest tightness, dizziness and other discomforts, and after resting the heart rate will soon return to normal, in this case, the general will not have an impact on the body.
2. If the heart rate stays at 170 beats/minute for a long time after strenuous exercise, it will affect the contraction and diastolic function of the heart muscle and lead to ischemia and hypoxia, which will cause irreversible damage to the heart, brain and other organs, and this will be harmful to the body. If the patient himself is combined with cardiac system diseases, after strenuous exercise, sympathetic nerve excitation, heart rate rises, increasing the burden on the heart, may induce heart failure or arrhythmia, serious life-threatening.
Prolonged heart rate at 170 beats / min will have a harmful effect on the body, if the heart rate is elevated and accompanied by uncomfortable symptoms, we should go to the hospital in a timely manner to avoid delaying the condition.
