Do heart meds cause low blood sugar in kids? new study investigates

This observational study looks at how often low blood sugar (hypoglycemia) occurs in children under 7 with Long QT syndrome who take the beta-blocker propranolol. Researchers will use a continuous glucose monitor for 10 days during healthy times and during an infection. They will compare results with healthy siblings to see if the medication raises the risk of low blood sugar, which could affect well-being and development.
