Slow Heart Rate (Bradyarrhythmia)

Bradyarrhythmia describes slow heart rate, typically defined as a rate of less than 60 beats per minute.
 
The electrical impulse that signals your heart to contract in a synchronized manner begins in the sinoatrial node (SA node), which is your heart's natural pacemaker. A bradyarrhythmia is a slow heart rate due to problems with the SA node's pacemaker ability, or some interruption in conduction through the natural electrical pathways of the heart.
 
When your heart rhythm is too slow, this can cause dizziness, fatigue, feelings of lightheadedness, fainting or near-fainting spells.
