Bronny James has been discharged from Cedars-Sinai Medical Center and is resting at home, three days after the 18-year-old son of LeBron James went into cardiac arrest. Dr. Merije Chukumerije, a consulting cardiologist for Bronny James, said in a statement issued by the hospital Thursday that James was “successfully treated for a sudden cardiac arrest” thanks to “the swift and effective response by the USC athletics’ medical staff” after the incident Monday at the University of Southern California’s Galen Center, where James was participating in basketball practice.
