Abnormally Slow Heartbeat (Bradycardia)
What is bradycardia?
Bradycardia means that the heart beats too slowly, usually less than 60 beats per minute. As a result, your body doesn’t get enough oxygen and nutrients.
It may be caused by a problem with specialized tissue called the sinus or S-A node. This tissue is your heart's “natural pacemaker”. Or the problem could relate to your heart's electrical pathways.
Some people don’t have any symptoms, and if they do, they may be subtle. Others may feel tired, light-headed or dizzy — and may faint.
Your doctor will probably do an electrocardiogram (ECG) test to look for heart rhythm problems.
How is a slow heartbeat treated?
If you have symptoms, you will likely need treatment. Doctors may recommend medications, a pacemaker or both. A pacemaker is an electronic device that sends electrical impulses to the heart to restore a normal heartbeat.
