FIGURE 1  Frequent VP, VT (A) ; complete RBBB and inverted T wave in leads V1-V6 (B).
RBBB: complete right bundle branch block; VP:ventricular premature; VT:ventricular tachycardia
FIGURE 2  No significant abnormalities in the standard apical four-chamber view (A) and parasternal four-chamber view (B).
FIGURE 3  Bulge and akinesia was observed at the RV apical segment of the lateral wall on right ventricular-focused view and basal segment of the inferior wall on RV inflow tract view (A, B), with respectively decreased RV regional longitudinal strain (green curve in C, light blue and yellow curve in D); RT-3DE vividly showed apical regional bulge and RT-3DE-RVEF decreased (E); Global longitudinal strain of LV decreased, especially at apex, posterior septum and posterior wall of LV (F).
RV: right ventricle; RT-3DE: Real-time three-dimensional echocardiography; RT-3DE-RVEF: RV ejection fraction on Real-time three-dimensional echocardiography; LV: left ventricle
FIGURE 4  CMR-LGE on both ventricles. Especially, on the 4-chamber long axis view showed CMR-LGE in the apical and lateral wall of RV, and posterior septum, posterior lateral wall of LV myocardial replacement of fatty issues, corresponding to the areas of abnormal strain on 2DSE.
CMR-LGE: late-gadolinium-enhancement on cardiac magnetic resonance; LV: left ventricle; RV: right ventricle; 2DSE: two-dimensional strain echocardiography
