Screening for Unrecognized Heart Disease in Other Settings Significant efforts have been undertaken in recent years to screen for heart diseases that may result in sudden death in children, particularly in athletes and in those taking stimulant medications. The incidence of sudden death due to unrecognized heart disease in a child between 1 and 20 years of age has been reported in the range of 1:100,000 per year.9 The sudden death of a
