Theoretically, the faster the average heart rate, the shorter the life expectancy. However, in reality, there are many influencing factors, such as living habits, dietary habits, etc., so there is not a direct relationship between fast and slow heart rate and life expectancy. Theoretically, the faster the resting heart rate, the greater the oxygen consumption per unit of time, the easier it is to cause metabolic abnormalities in the heart, which can lead to various types of cardiovascular diseases. Therefore, fast resting heart rate is one of the important factors that increase the risk of cardiovascular diseases. However, the conclusion of the current study that “fast resting heart rate increases the risk of death” is only an epidemiological statistic and has not yet been unanimously recognized by the academic community. It is important to note that each person is different, and it is not possible to generalize, but it is advisable to consult a doctor if you have problems with your heart rate.
