Disease description:

Doctor's answer (1)
Dr. Wang Mingxuan
Sinus bradycardia may be caused by conditions such as hypothyroidism or myocardial infarction. Hypothyroidism is usually due to a deficiency of thyroid hormones, leading to a decreased basal metabolic rate in patients, with main symptoms including fatigue and slowed heart rate, which can result in sinus bradycardia. Patients are advised to engage in appropriate physical exercise regularly, which is beneficial for their health.
