Atrial fibrillation, also known as AFib, happens when your normal heart beat or rhythm is changed and may not be able to pump enough blood. About 1% of Americans have AFib.
Millions of people with long-lasting AFib live quite well, said Gordon F. Tomaselli, MD, director of the Division of Cardiology at Johns Hopkins University School of Medicine and a past president of the American Heart Association. "It's very possible to live a normal life for many years."

Listen to your lungs
through a stethoscope for wheezes or other sounds of lung disease or fluid

Why It Is Done
Some symptoms of atrial fibrillation, like lightheadedness, palpitations,
and chest pain, can be caused by other health problems. A medical history and physical exam will help your doctor find out what is causing your symptoms.
You will need further tests, such as an electrocardiogram (EKG or ECG), to diagnose atrial fibrillation.
Findings of the history and physical exam may
include the following.
Breathing, heart rhythm, and heart rate are
Blood pressure is normal.
No sign of fluid
buildup is present.
Findings that may suggest atrial fibrillation or
heart failure include:
A rapid or irregular pulse and irregular
Shortness of breath, especially during
Fatigue, weakness, and
Sounds in the lungs that may indicate a backup of
fluid in the lungs due to heart failure.
Swelling in legs, ankles,
or feet or in the lower back.
Swollen neck veins or a noticeable
change in how the blood moves through the blood vessels in the neck.
Further testing will be done if your history and physical
exam suggest atrial fibrillation.

doctor with detailed information about your past health and
Other health problems that can cause symptoms similar to atrial fibrillation include other abnormal heart rhythms, coronary artery disease, and imbalances in your blood.
