Sinus bradycardia, also called sinus bradycardia, usually does not require treatment if the patient has no symptoms, such as dizziness or blackness in front of the eyes. If a patient with a heart rate that is too slow experiences dizziness or blackness in front of the eyes due to insufficient blood displacement from the heart, treatment can be given with medications such as atropine or isoprenaline, which are temporary drugs with significant side effects. For a heart rate that is too slow, pacemaker therapy may be considered. If the heart rate is not particularly slow and the patient is symptomatic, you can apply Chinese herbal medicine such as Xin Bao Wan or Ning Xin Bao Capsules to treat the symptoms and raise the heart rate. Patients with sinus bradycardia are often accompanied by sinus arrhythmia and often occur in healthy young people or athletes, during sleep, and from other specific causes, such as cerebral hemorrhage, severe hypoxia, hypothermia, hypothyroidism, and the application of anti-arrhythmic drugs, so these causes should be taken into account when treating them.
