Dizziness and Tetralogy of Fallot: Understanding the Connection

Tetralogy of Fallot (TOF) is a congenital heart defect that affects the structure of the heart. It is characterized by four abnormalities: a hole between the ventricles (ventricular septal defect), a narrowing of the pulmonary valve (pulmonary stenosis), an overriding aorta, and an enlarged right ventricle.

Dizziness is not a typical symptom of TOF, but it can occur in some cases. This is usually due to a decrease in blood flow to the brain, which can be caused by the narrowing of the pulmonary valve or the overriding aorta. In some cases, dizziness may also be caused by an arrhythmia, which is an abnormal heart rhythm.

If you are experiencing dizziness and have been diagnosed with TOF, it is important to see your doctor to rule out any underlying causes. Your doctor may recommend medications or surgery to treat your TOF and relieve your symptoms.
