Sinus Bradycardia and Sick Sinus Syndrome

By November 8, 2013

Follow me on:

Sinus bradycardia is a slow heart rate that results when the heart's sinus node slows the production of the electrical impulses that control the heart rate.  There are many potential causes for sinus bradycardia,  including the fact that in many cases a slow heart rate is perfectly normal.

However, when the sinus node is producing an inappropriately low heart rate, especially if the slow heart rate is producing symptoms (fatigue, lightheadedness, or even lost of consciousness), that condition is often called sick sinus syndrome.
