Listening with a stethoscope usually reveals a heart murmur (the sound of the blood crossing the hole). The loudness of the murmur is related to the size of the defect and amount of blood crossing the defect.
|
 |
The physician will listen to the heart with a stethoscope(auscultation) to detect a heart murmur. X rays, electrocardiogram(ECG), and echocardiography can all be used to evaluate ventricular septal defect.

Detailed information on chest x-rays, including reasons for the procedure X-rays are made by using low levels of external radiation to produce images of the body, the organs, and other internal structures for diagnostic purposes. X-rays pass through body structures onto specially treated plates (similar to camera film) and a "negative" type picture is made. The more solid a structure is, the whiter it appears on the film. For this reason, bones appear very white on an x-ray film, but less dense tissue such as muscle, blood, skin, and fat appears darker.
