Bradycardia: Controlling a slow heart rate

Irregular heart rhythm. It’s a common cardiac condition, but most people with this problem experience a heart beating too fast. A less common type of arrhythmia (abnormal heart rhythm) is known as bradycardia. This condition happens when the heart rate is too slow. Bradycardia is a heart rate of less than 60 beats per minute. It can be caused by various problems, including problems with the heart's sinus node, which acts as a kind of natural pacemaker.

It may also be caused by problems in the conduction pathways of the heart. This means that electrical impulses are not being conducted from the atria to the ventricles, so the heart’s regular rhythm is disrupted. Other causes include metabolic problems such as hypothermia, or damage from a heart attack or heart disease.

Do you know about atrial fibrillation?

That strange, fluttery feeling in your chest could be serious.

It could be atrial fibrillation (A-fib), a type of abnormal heart rhythm (arrhythmia) that causes the heart to pump blood ineffectively. A-fib is the most common type of persistent heart arrhythmia and it affects almost 5 million Americans.

What is a heart arrhythmia?

 Did you think about your heartbeat today?

If you’re like most Americans, you probably didn’t give it much thought, even though your heart was beating constantly, anywhere from 60 to 100 beats a minute.

Normally, the heart’s electrical system causes the heart muscle to contract in a regular, controlled pattern. However, a problem anywhere along the electrical pathway causes a disturbance in the heart rhythm. This could lead to an irregular heart rhythm or a heart rate that’s too fast or too slow.
