Chest X-ray: X-ray images help to visualize the condition of the lungs and heart. If the heart is enlarged on an X-ray, other tests will usually be needed to find the cause. A useful measurement on X-ray is the cardio-thoracic ratio, which is the transverse diameter of the heart, compared with that of the thoracic cage. [24]
Echocardiography, which is the diagnostic test of choice, often demonstrates an enlarged pericardium or collapsed ventricles. A large cardiac tamponade will show as an enlarged globular-shaped heart on chest x-ray. During inspiration, the negative pressure in the thoracic cavity will cause increased pressure into the right ventricle. This ...
A chest radiograph, chest X-ray (CXR), or chest film is a projection radiograph of the chest used to diagnose conditions affecting the chest, its contents, and nearby structures. Chest radiographs are the most common film taken in medicine.
Chest X-rays are also often taken when hemopericardium is suspected and would reveal an enlarged heart. [6] Other observable signs include rapid heart rate, jugular venous distension, low blood pressure, and pulsus paradoxus. [6]
Generalized enlargement of the heart is seen upon normal chest X-ray. Pleural effusion may also be noticed, which is due to pulmonary venous hypertension. [28] The electrocardiogram often shows sinus tachycardia or atrial fibrillation, ventricular arrhythmias, left atrial enlargement, and
On a chest X-ray, the normal heart silhouette should have a clear and defined outline. However, in cases of pericardial effusion, the accumulation of fluid within the pericardial sac causes the heart to appear enlarged and assumes a shape that is reminiscent of a water bottle, with relatively smooth cardiac contours.
