It is possible for the bradycardia to recover on its own. For example, if the bradycardia occurs while the patient is in deep sleep and the patient wakes up or is awake, the heart rate is naturally within the standard range, and this also belongs to the patient recovering the heart rate on its own. Some patients may have suffered an acute inferior wall myocardial infarction at the time, and their heart rate will gradually improve after active and effective treatment. If the bradycardia is caused by hypothyroidism or hyperkalemia, it needs to be combined with appropriate treatment to help improve the bradycardia, such as hyperkalemia, which in severe cases needs to be combined with dialysis treatment, or if it is not very serious, it can be combined with oral potassium lowering resin and static diuretics to lower the serum potassium concentration, thus improving the bradycardia. This can be combined with oral potassium lowering resins and sedative diuretics to lower the serum potassium concentration and improve the bradycardia.
