After waking up in the morning, the pulse rate is only 50, suggesting that the heart rate is low, the reason can be non-pathological factors and pathological factors, non-pathological factors generally do not require special treatment, while pathological factors need to be dealt with according to the specific causes. 1. Non-pathological factors: for people who have been exercising for a long time, some elderly people, and people who are thin and weak may have a low pulse rate after waking up in the morning, which can be as low as 50 beats/minute. Generally, there are no obvious symptoms, and the heart rate will be raised after appropriate activities, so it can be followed up for observation and does not require any special treatment. 2. Pathological factors: the diseases that cause the heart rate to decrease after waking up in the morning include arrhythmia, hypothyroidism, increased intracranial pressure, etc. In the case of arrhythmia, such as sinusoidal arrhythmia, the heart rate will increase after appropriate activities. Arrhythmia such as sinus bradycardia, atrioventricular block can cause heart rate reduction, if there are obvious symptoms such as chest tightness, palpitations, etc., can be appropriate to elevate the heart rate of drugs, such as atropine, scopolamine and so on. Hypothyroidism can reduce the synthesis and secretion of thyroid hormone to reduce the body’s metabolism, resulting in a reduced heart rate, the need for thyroid preparation replacement therapy, such as oral thyroid tablets or levothyroxine. When the heart rate is lowered by increased intracranial pressure, which causes ischemia of brain tissue and stimulates the circulation, dehydrating drugs such as mannitol, glycerol fructose, etc., and surgical craniotomy to lower the cranial pressure if necessary, etc., can be used. If there is a significant decrease in heart rate, it is recommended to consult a doctor in a timely manner, under the guidance of a physician to improve the relevant examinations, to clarify the cause of the disease, to carry out causal treatment, do not unauthorized treatment or use of drugs to avoid adverse reactions.
