An insignificant increase in heart rate with exercise may be a normal physiologic response, or it may be caused by problems such as abnormal sinus node function and angina pectoris.
1. Physiological response: If a person engages in physical exercise for a long period of time, the heart function will be enhanced and the ejection of blood will be sufficient. At the same time, people who insist on exercising are not prone to over-excitement problems, so the increase in exercise heart rate is not obvious.
2. Abnormal sinus node function: when the sympathetic nerve control of the heart rate is weakened, it is easy to cause the sinus node function abnormality, showing the problem of sinus bradycardia, and the increase in heart rate after exercise is not obvious.
3. angina pectoris: if the coronary artery blood supply is insufficient, it is easy to cause angina pectoris, and severe necrosis of cardiomyocytes, which affects the heart function, and heart rate increase after exercise is not obvious.
To summarize: there are many reasons why the heart rate increase after exercise is not obvious, if accompanied by other adverse symptoms, we must consult a doctor as soon as possible, and according to the doctor’s instructions for treatment.
