Figure 2 Examples of typical LQT2 T-wave patterns in the affected family members. (a) Low bifid T waves in the proband, QTc 500 ms. (b and c) Subtle bifid T waves in two other affected members, QTc of 500 ms and 480 ms, respectively. Overall, 87% of T1945+6C mutation carriers presented typical LQT2 T-wave patterns on baseline electrocardiogram.
