Sinus arrhythmia is divided into physiologic and pathologic (e.g., sinus tachycardia, sinus bradycardia, sick sinus node syndrome, etc.). If it is physiologic, no special treatment is needed; if it is pathologic, asymptomatic patients can be reviewed regularly in outpatient clinics; if there are symptoms of sinus bradycardia/tachycardia, medications (e.g., atropine, metoprolol, etc.) need to be taken to increase the patient’s heart rate.
Sinus arrhythmia is usually a change in the rhythm of the atria and ventricles of the heart caused by irregular electrical impulses to the sinus node. Typically, sinus arrhythmias are not accompanied by clinical symptoms and therefore are of little significance and generally do not require specific treatment after evaluation by a cardiologist.
If sinus bradycardia is evident, it is treated with heart rate-enhancing drugs such as atropine and isoprenaline. For patients with severe sick sinus node syndrome, pacemaker therapy may be necessary.
If there is significant sinus tachycardia, treatment with medications such as metoprolol and diltiazem alone or in combination may be required, and catheterized radiofrequency ablation may be considered to improve sinus node function if necessary.
If the patient has sinus arrhythmia, it is recommended to go to the regular hospital for appropriate treatment.
