TOF is typically diagnosed through a combination of physical examination and diagnostic tests. Key diagnostic tools include:
- Echocardiogram: An ultrasound of the heart that can visualize the anatomical defects. - Chest X-ray: Can reveal the characteristic "boot-shaped" heart due to right ventricular hypertrophy. - Electrocardiogram (ECG): Can show right ventricular hypertrophy and other electrical abnormalities. - Pulse oximetry: Measures the oxygen saturation in the blood and can indicate cyanosis.
