Figure 2 Electrocardiograms Associated With the 3 Ballooning Variants of Stress Cardiomyopathy After Drug Administration
T-wave inversion, Q waves, and corrected QT interval (QTc interval) prolongation were seen with the apical variant (A). Nonspecific T-wave abnormalities were seen with the midventricular variant (B). Broad upright T waves and QTc interval prolongation were characteristic of the basal variant (C). These electrocardiogram patterns evolved within 24 to 48 h of drug administration.
