Electrocardiogram
The ECG may be normal in the newborn, but in older patients signs of right ventricular hypertrophy may be seen. After a mustard operation rhythm disturbances such as bradyarrhythmias may be seen.

The right axis deviation is moderate or absent, in patients with a large VSD, low pulmonary vascular resistance, and LV volume overload. On the other hand, the right axis deviation is greater if there is a reduced pulmonary arterial blood flow and reduced LV volume as a result of pulmonary vascular disease or pulmonic stenosis.
