What to watch for

Recognising the signs

Inherited Cardiac Conditions can be silent; many children and adults look healthy and feel well. However, there are often subtle signs that a heart condition may be present. Recognising them early can save lives. This page outlines the heart condition symptoms and signs that warrant a conversation with your healthcare provider.

Key points for parents

Heart condition symptoms can be subtle or rare. Many children with ICCs feel perfectly well most of the time.

Family history is critical. Even if a child shows no symptoms, a family history of SADS or heart rhythm problems may indicate risk.

Trust your instincts. If something feels unusual or off, get it checked.
