Do nodoventricular accessory pathways in PRKAG2-dependent familial preexcitation syndrome reveal a disorder in cardiac development?
Preexcitation associated with the R302Q mutation in PRKAG2 is associated with Mahaim fibers. These findings support the novel insight that PRKAG2 may be involved in the development of the cardiac conduction system.
Most school-aged children who visited a pediatric primary care clinic of a large urban hospital had directly experienced violence as witnesses and/or victims.
