Final answer:
ECG findings in pulmonary valve stenosis can include an amplified P wave, and signs of right ventricular hypertrophy such as an enlarged R wave in lead V1. Echocardiography is used alongside ECG for diagnosis and assessment of the condition.
Step-by-step explanation:
ECG findings in pulmonary valve stenosis may not be as specific as in some other heart conditions, but can include certain abnormalities. Some changes that might suggest pulmonary stenosis include an amplified P wave, indicating atrial enlargement due to the increased work the right atrium must perform to push blood through the narrowed valve.
Additionally, there may be signs of right ventricular hypertrophy, such as an enlarged R wave in lead V1 and a deep S wave in lead V6. These findings signify that the right ventricle is working harder to compensate for the obstructed blood flow through the pulmonary valve. While ECG offers a non-invasive method to detect these changes, echocardiography is typically used to confirm the diagnosis of pulmonary valve stenosis and assess its severity.
