Final answer:

ECG findings for a large VSD often indicate right ventricular hypertrophy including right axis deviation, enlarged R waves in right precordial leads, and an increased P wave amplitude showing right atrial enlargement.

Step-by-step explanation:

The electrocardiogram (ECG) findings for a large ventricular septal defect (VSD) may not be specific, but they can indicate changes in the heart's structure as a result of the defect. A large VSD typically causes overloading of the pulmonary circulation and hypertrophy of the right ventricle. On an ECG, this may manifest as right ventricular hypertrophy, with features such as right axis deviation, enlarged R waves in the right precordial leads, and an increased P wave amplitude indicating right atrial enlargement. The detailed vector analysis of a 12-lead ECG may show other signs of ventricular strain or pressure overload.
