The efficacy of ECG screening of newborns for LQTS has been demonstrated in Italy. Furthermore, within the national healthcare system in Italy, universal ECG screening in newborns (<30 days old) is cost-effective. The U.S. debate for universal LQTS screening started in the mid-2000's. In a 2007survey completed by North American pediatric cardiologists, 27% favored optional ECG screening of newborns, whereas 11% supported mandatory screening (363 responses, 35% response rate). There may be stronger support for universal screening, now that more data are available.
