Figure 1 Electrocardiographic examples of the 3 most common inherited heart rhythm disorders. (A) The 3 most common forms of long QT syndrome, with exercise-provoked corrected QT prolongation in LQT1, notched asymmetric T waves in LQT2, and a normal but deferred QT in LQT3. (B) The 3 patterns of Brugada electrocardiogram, with clinical concern restricted to a spontaneous or provoked type 1. (C) Symmetric T wave inversion in the right ventricular leads that is variably seen in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). See text for discussion.
