Sick sinus syndrome

  • Alternative Names

    Bradycardia-tachycardia syndrome; Sinus node dysfunction


    Treatment

    Treatment may not be necessary if you do not have any symptoms. Your doctor may review the medicines you take to make sure they are not making your condition worse. Do not stop taking any medication unless told to do so by your doctor.

    A permanent implanted pacemaker may be needed if your symptoms are related to bradycardia (slow heart rate).

    A fast heart rate (tachycardia) may be treated with medications. Sometimes a procedure called radiofrequency ablation is used to cure tachycardia.
