When to seek medical advice

By Mayo Clinic staff

You should see your doctor if you suddenly faint during physical exertion or emotional excitement or after use of a new medication.

Because long QT syndrome can occur in families, see your doctor to be tested for long QT syndrome if a close relative (your parent, sibling or child) has been diagnosed with long QT syndrome.
