Bradycardia minor remedies are ineffective, unreliable and have no scientific basis. Bradycardia, clinically known as bradycardia, the main treatment includes symptomatic treatment, causative treatment. 1. Symptomatic treatment. Most of the sinus bradycardia, no clinical manifestations, generally do not need treatment. If there is organic heart disease, such as myocardial infarction, accompanied by severe bradycardia, atropine can be used to elevate the heart rate. The heart rate elevating drug isoprenaline can also be used to increase the heart rate. For patients with damaged sinus node and poor drug therapy, pacemakers can be used. 2. Treatment of the cause. For bradycardia caused by hypothyroidism, patients with general symptoms can take levothyroxine, and patients with iodine deficiency can take iodine supplements. For bradycardia caused by hyperkalemia, the first step is to lower the potassium level. Potassium-lowering drugs such as insulin and glucose can be taken, and the intake of potassium-containing foods is prohibited. The diagnosis of bradycardia should be confirmed and the treatment should be carried out according to the doctor’s requirements. Medications should be administered in strict accordance with the doctor’s requirements.
