Slow heartbeat means the heart rate is lower than 60 beats per minute, and its causes are physiological and pathological. 1. Physiological reasons: some healthy young people and professional athletes may have a slow heartbeat, these people may have a heart rate lower than 60 beats per minute all the time, there are no uncomfortable symptoms, and there is no disease, there is no need for special treatment. In addition, the heart rate of normal people during sleep can be between 45-60 beats per minute, which is also a normal phenomenon. 2. Pathological reasons: clinically, many diseases can cause slow heartbeat, such as increased intracranial pressure, myocardial infarction, atrioventricular block, sick sinus node syndrome, cardiomyopathy, hypothyroidism, cervical spine trauma and so on. When a slow heartbeat occurs, care should be taken to distinguish whether it is physiologic or pathologic. For physiologic slow heartbeat, no treatment is needed. For pathologic slow heartbeat, you should go to regular hospitals for early diagnosis of the cause of the disease and reasonable treatment under the guidance of a professional doctor in order to reduce the adverse effects of the disease.
