Figure 1 Distinctive T-Wave Patterns in the 3 Major LQTS Genotypes

T-wave morphology by LQTS genotype: LQT1: typical broad-based T-wave pattern (corrected QT [QTc] 570 ms); LQT2: typical bifid T-wave (QTc 583 ms); and LQT3: typical late-onset peaked/biphasic T-wave (QTc 573 ms). Reprinted, with permission, from Moss et al. (17).
