Heart rhythm monitoring in young people taking psychiatric medications

This trial is studying how psychiatric medications can sometimes affect the heart's electrical rhythm in children and teenagers. Researchers want to understand how often this happens, how severe it is, and when doctors should check for it during treatment. They'll do heart tests (called ECGs) at the beginning of treatment and at several points over the next year.

Some psychiatric medications are known to occasionally affect how the heart's electrical system works, which can be dangerous. Right now, doctors do a heart test before starting the medication, but there are no clear guidelines about when to repeat the test during treatment or what warning signs to watch for.
