Bradycardia

The number of normal people's heartbeat is 60 to 100 beats per minute, and less than 60 is called bradycardia. There are several types of bradycardia, the most common of which is sinus bradycardia. Sinus bradycardia can be divided into pathological and physiological. Physiological sinus bradycardia is a normal phenomenon. Generally, heart rate and pulse are between 50 and 60 beats per minute. Athletes may have a heart rate of 40 beats without treatment. They are common in normal people who sleep and have more physical activity. Heart rate or pulse less than 50 times is pathological and requires treatment. In severe cases, a pacemaker should be installed to speed up the heart rate.
