A slow heart rate might occur because the sinus node:In some people, the sinus node problems result in alternating slow and fast heart rates (bradycardia-tachycardia syndrome).Bradycardia can also occur because electrical signals transmitted through the atria aren't transmitted to the ventricles (heart block, or atrioventricular block).Heart blocks are classified based on the degree to which signals from the atria reach your heart's main pumping chambers (ventricles).A key risk factor for bradycardia is age.

The signal then travels through the atria to the atrioventricular node and then passes into the ventricles, causing them to contract and pump out blood.Bradycardia, shown on the right, is a slower heart rhythm that may occur because the sinus node in the heart may be discharging electrical impulses at a slower than normal rate.
