SCA is a sudden and unexpected pulseless condition attributed to cessation of cardiac mechanical activity. It is usually caused by ventricular fibrillation, an abnormality in the heartâs electrical system. When SCA occurs, blood stops flowing to the brain, the heart, and the rest of the body, and the person collapses.
Because sudden cardiac arrest can affect any seemingly healthy student, we recommend that parents partner with their pediatricians to evaluate their childâs need for a more detailed cardiac evaluation.

Long QT syndrome is an often unrecognized congenital condition that predisposes the child to an abnormality in the heart's electrical system, which can lead to SCA. This is a genetic disease that affects 1 in 7,000 young people.
