Explain The ECG and cheast X- Ray?

The ECG and Chest X-ray: If there is a suspicion of heart disease on basis of the history or physical examination an ECG and a chest X-ray should be obtained. The X-ray also provides information about the location of abdominal organs (for determination of the situs) and the aortic arch. Beyond the neonatal period, a normal ECG and chest X-ray makes the diagnosis of a hemodynarnically significant heart defect unlikely. In newborns, however, ECG and chest X-ray changes, may take a few days to evolve. For the newborn, particularly in the first few days a "normal" ECG and a normal X-ray does not rule out serious heart disease.

The Importance of an Accurate and a Complete Diagnosis in a Patient with CHD. This, arguably, is one of the most important responsibilities of the paediatric cardiologist. The implications of an incomplete or incorrect diagnosis are often potentially serious, and sometimes, fatal. It is useful to remember that if there is one developmental defect in the heart, there may be others that need to be addressed. Very often, this is indeed the case.
