It is not scientific to say that people with slow heartbeats live longer. The normal range of heart rate is 60 to 100 beats per minute, below 60 beats per minute is bradycardia.
Heart rate is slightly lower than normal, but there is no obvious discomfort, sometimes seen in athletes or people engaged in heavy physical labor.
Although this type of people have a slow heartbeat, but the heart’s contraction capacity is strong, daily to ensure that all parts of the body on the demand for blood supply, the heart’s reserve function is stronger, may be able to have a certain positive impact on life expectancy, but there is not yet a clear scientific basis.
However, when the heartbeat is significantly lower, it is easy to lead to a reduction in cardiac output, at this time, the periphery will be ischemia and hypoxia symptoms, and even serious cases can occur in important organs of ischemia, such as myocardial ischemia, cerebral ischemia, which can be life-threatening.
