What is AFib ?

Atrial fibrillation – sometimes referred to as AFib or AF – is the most common type of cardiac arrhythmia (abnormal heart rhythm).4

What happens during AFib?

During AFib, the upper chambers of the heart, known as the atria, beat rapidly or in an uncontrolled manner.5 Watch this video to see the difference between a heart in normal rhythm and a heart in AFib.

How does the heart work?

The purpose of the heart is to pump blood throughout the body to deliver a continuous supply of oxygen and other nutrients to the brain and other vital organs. The heart is a muscle, composed of four chambers: two upper chambers, called the atria, and two lower chambers, called the ventricles, each occupying both the right and left side of the heart.

The heart has an electrical system that coordinates the work of the heart chambers (heart rhythm) and controls the frequency of beats (heart rate). AFib is a condition that interrupts the normal flow of the electrical system, which is typically reflected on an EKG.5,6

Abnormal Heart Rhythm

When the heart beats erratically, it does not pump blood as efficiently as it should. A person may feel ill or experience other AFib symptoms because oxygen isn’t being properly delivered to all parts of the body. However, 15-30% of patients with AFib do not feel any symptoms.7

As with any medical treatment, individual results may vary. Only a cardiologist or electrophysiologist can determine whether ablation is an appropriate course of treatment. There are potential risks including bleeding, swelling or bruising at the catheter insertion site, and infection. More serious complications are rare, which can include damage to the heart or blood vessels; blood clots (which may lead to stroke); heart attack, or death. These risks need to be discussed with your doctor and recovery takes time. The success of this procedure depends on many factors, including your physical condition and your body's ability to tolerate the procedure. Use care in the selection of your doctors and hospital, based on their skill and experience.
