A pulse rate of 45 beats/minute belongs to bradycardia, which may lead to ischemia of the heart, kidney, brain and other vital organs in severe cases, and may even bring about a life-threatening situation.
1. Bradycardia refers to a heart rate of less than 60 beats/min. In general, a heart rate of 50-60 beats/min belongs to a mild form of bradycardia, which is generally less harmful and may cause symptoms of poor blood supply during strenuous exercise, such as chest tightness and fatigue, etc., but it can be relieved after rest.
2. However, if the heart rate is less than 50 beats/minute for a long time, symptoms such as chest tightness and shortness of breath may occur, affecting the patient’s quality of life. If the heart rate is less than 40 beats/minute, it may cause insufficient blood supply to the patient’s heart, brain, kidneys and other important organs, which may lead to the patient’s death in serious cases.
If you find bradycardia, you should seek medical examination and treatment in time.
