Overview
A chest-x-ray is not usually used a s the main diagnostic tool for atrial fibrillation; nevertheless, it could be abnormal when conditions such as pulmonary diseases or heart failure is the etiology of atrial fibrillation.
Chest X ray
- A chest x-ray is generally performed if a pulmonary cause of atrial fibrillation or heart failure is suggested. This may reveal an underlying problem in the lungs, the blood vessels in the chest, and the size of the heart.
- In particular, if an underlying pneumonia is suggested, then treatment of the pneumonia may cause the atrial fibrillation, hence it is important to perform a chest x-ray when such a condition is suspected.
- Chest x-ray is helpful in demonstarting both lung parenchyma and pulmonary vasculature.[1]
- If heart failure is suspected as the etiology of atrial fibrillation, then chest x-ray findings could be helpful. Nevertheless, an abnormal chest X-ray only has 57% sensitivity, and 83% negative predictive value for heart failure. Therefore chest x-ray findings should be confirmed with other siagnostic tool as well. [2]
- The following are some findings that can be reported in chest x-ray, if heart failure is the etiology of atrial fibrillation:[2][3]
- Redistribution in flow of upper zone of the lung
- Lung interstitial edema
- Bilateral pleural effusion
- Cardiomegaly
