Symptoms
Exact symptoms in people with Tetralogy of Fallot can vary, depending on how much the pulmonary artery is blocked. Typical signs include shortness of breath, fatigue, poor exercise tolerance, and cyanosis. They tend to become worse over time. In more severe cases, serious cyanosis might require urgent medical treatment. In the early stages, these symptoms are not clear, making it quite hard to diagnose. Therefore, parents need to understand the condition and notice these symptoms in their children. [5]
