Sick sinus syndrome is the name given to a group of arrhythmias that occur because the normal pacemaker of the heart (the sinus node) does not work properly. Sick sinus syndrome is also called sinus node dysfunction.
For more information on other types of sinus node problems, see Types of Bradycardia.
Sick sinus syndrome can occur for various reasons. It most commonly results from the effect of age on the sinus node. As we get older, scarring of the sinus node can occur and, in some people, it can be so severe that it causes this syndrome.
Various irregular heart rates (arrhythmias) or combinations of arrhythmias can occur in this condition. People with this syndrome can have slow arrhythmias or a combination of fast and slow arrhythmias. These include:
Treatment of sick sinus syndrome depends on what is causing it. Treatment also depends on the symptoms. If the syndrome doesn't cause symptoms, it may not be treated. Treatment may be a pacemaker. You and your doctor can decide what treatment is right for you.
In tachy-brady syndrome, also called tachycardia-bradycardia syndrome, the heart sometimes beats too quickly (tachy) and sometimes beats too slowly (brady). This abnormal heart rhythm problem is often seen in people who have been diagnosed with atrial fibrillation. It can occur when the heart's natural pacemaker is damaged.
