Figure 1.
A 12-lead electrocardiogram showing giant, inverted T waves (> 10 mm) in V4-V6 and QT interval prolongation (QTc = 506 ms)
Figure 2.
Cardiac magnetic resonance imaging demonstrating localized apical hypertrophy and the “ace of spades” sign at end-diastole (arrow). Maximum left ventricular (LV) wall thickness is 19 mm in the anteroseptal segment. Focal late gadolinium enhancement is seen in the apical, septal, and basolateral walls with total scar burden involving 6% of LV mass.
Figure 3.
A 12-lead electrocardiogram showed a corrected QT interval measuring 463 ms and the same inverted T-waves in the anterolateral leads.
