Overview

Sick sinus syndrome can result in many abnormal heart rhythms (arrhythmias), including sinus arrest, sinus node exit block, sinus bradycardia, and other types of bradycardia (slow heart rate). Sick sinus syndrome may also be caused by a variety of conditions including but not limited to myocardial infarction, atrial fibrillation, drugs or toxins, infections,medications, electrolyte abnormalities, hypothermia, hypoxemia, hypercarbia, and acidosis.

Causes
