Causes and treatment of sinus bradycardia

Bradycardia generally refers to bradycardia, sinus bradycardia is generally due to hypothyroidism, meningitis, cardiomyopathy and other diseases, need to be treated according to the etiology. 1, hypothyroidism hypothyroidism patients due to insufficient thyroid hormone synthesis basal metabolic rate decline performance, such as heart rate slowed down, constipation, fatigue, memory loss and so on. Patients can supplement thyroid hormone with levothyroxine sodium tablets, thyroid tablets and other drugs to restore thyroid function to normal and improve bradycardia. 2. Meningitis Meningitis is usually caused by infection with pathogenic microorganisms and can lead to increased intracranial pressure and vagus. Increased central excitability leads to pathological sinus bradycardia. Patients can use mannitol, glycerol fructose, furosemide and other drugs to reduce intracerebral pressure, alleviate the disease.3, cardiomyopathy cardiomyopathy patients will appear arrhythmia phenomenon, such as bradycardia, tachycardia, dizziness, dyspnea, etc., the cause of cardiomyopathy is not completely clear, may be related to genetic, viral infection, immune dysfunction and other factors. Patients can be treated with drugs such as digoxin, levosimendan, dopamine, etc. to increase myocardial contractility and relieve symptoms of bradycardia. If systemic blood flow is insufficient or conventional treatment fails, surgery such as ventricular septal resection or heart transplantation can be performed.
