- if the defect is small the ECG may be normal
- while the pulmonary resistance is low the volume overload of the left ventricle produces features of left ventricular hypertrophy
- as the pulmonary resistance increases right ventricular hypertrophy occurs
- as pulmonary and systemic vascular resistances become balanced the left ventricular volume overload is lost. The left ventricular hypertrophy regresses leaving pure right ventricular hypertrophy
