Overview
Sick sinus syndrome is a collection of heart rhythm disorders that include:
- Sinus bradycardia -- slow heart rates from the natural pacemaker of the heart
- Sinus pauses or arrest -- when the natural pacemaker of the heart stops working for periods of time
People with these disorders may also have other abnormal heart rhythms, such as:
- Atrial tachycardia -- fast heart rate that starts in the upper chambers of the heart (atria)
- Bradycardia-tachycardia -- alternating slow and fast heart rhythms
What are the symptoms of Sick sinus syndrome?
Usually, no symptoms occur. Symptoms that do occur are may mimic those of other disorders.
Symptoms may include:
- Chest pain or angina
- Confusion or other changes in mental status
- Fainting or near-fainting
- Fatigue
- Dizziness or light-headedness
- Sensation of feeling the heart beat (palpitations)
- Shortness of breath, possibly only with activity
