Abstract excerpt

BACKGROUND: In children with long QT syndrome (LQTS), risk factors for cardiac events have been reported, but age-, gender- and genotype-related differences in prognosis remain unknown in Asian countries. METHODS AND RESULTS: The study examined clinical prognosis at age between 1 and 20 years in 496 LQTS patients who were genotyped as either of LQT1-3 (male, n=206). Heterozygous mutations were observed in 3 major...
