Sinus tachycardia without symptoms does not require special treatment. However, if the patient develops uncomfortable symptoms, such as panic, palpitation, etc., it is necessary to choose the treatment for the cause of the disease, and follow the doctor’s instructions to take medication such as propranolol, or catheter ablation treatment. 1. Treatment for the cause and removal of triggering factors: such as treating heart failure, correcting anemia, controlling hyperthyroidism, etc. 2. Drug therapy: beta-blockers and calcium channel blockers, such as propranolol and diltiazem, can be used singly or in combination. If these two drugs are not tolerated, sinus node inward current inhibitors, such as ivabradine, can be used. 3. Catheter ablation therapy: If medication is ineffective and there is no significant improvement in discomfort, catheter ablation therapy may be considered to improve sinus node function. If you need medication, you should go to the hospital for a clear diagnosis and be prescribed by a doctor, rather than blindly using medication on your own to avoid adverse effects on your body.
