Atrial Fibrillation
How is the disease diagnosed?
The diagnosis of atrial fibrillation begins with a medical history and physical exam. The healthcare provider may order tests, including the following:
blood tests to rule out problems causing the irregular heart rate
chest X-ray, to detect problems in the lungs
echocardiogram, which uses ultrasounds to look at blood flow in the heart
electrocardiogram, or ECG, which measures the electrical activity of the heart
