Abnormally Slow Heartbeat (Bradycardia)

Description

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.

What causes the heart to beat too slowly?
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.
How can I tell if I have bradycardia?
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.
What tests might I need?
Your doctor will probably do an electrocardiogram (ECG) test to look for heart rhythm problems.

Treatment

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.
