In most cases, ventricular septal defects are revealed after the birth of a child. By using a stethoscope, the doctor can listen to the rumble of the blood as it goes through the hole. This is called a murmur. At times even if you place your hand on your chest, you will feel a rumbling. This is called a thrill. Some VSDs are not diagnosed until adulthood. Diagnosis of a VSD includes:
Chest X-ray
Electrocardiogram
Echocardiogram
Cardiac MRI
