Sinus bradycardia does not require any special treatment if there are no significant symptomatic episodes. If an abnormal reaction occurs, it is recommended that patients with sinus bradycardia be treated with heart rate medication or a pacemaker. If the heart rate remains above 50 to 60 beats per minute and symptoms such as fatigue, dizziness, or shortness of breath do not occur frequently, sinus bradycardia does not require additional treatment and can be followed up with regular cardiac ultrasounds and electrocardiograms. If a patient with sinus bradycardia has a heart rate of less than 50 beats per minute or frequently experiences discomfort such as dyspnea or dizziness, the patient may be treated by taking heart rate medications, such as atropine, ephedrine, or isoproterenol, as a first step to alleviate the discomfort. For patients with severe low heart rate and atrioventricular block, especially third-degree atrioventricular block, the installation of a pacemaker can be considered. However, ancillary tests such as electrocardiograms and cardiac ultrasound are required to determine whether the patient is a candidate for the procedure before pacemaker installation. Most cases of sinus bradycardia do not require any special treatment, but it is still recommended to go to the hospital regularly for health checkups, especially heart checkups. Strenuous exercise is not recommended. If you feel unwell, please consult a doctor promptly.
