Key result
Computerized epicardial mapping in right ventricular hypertrophy revealed delayed right ventricular activation and repolarization, with significant correlations (r=0.56-0.90) between MAP90 and A-R intervals.

RV activation/repolarization patterns in RVH support SI model of T waves; hypothesis-generating for broader populations.

What are the epicardial activation and repolarization patterns in patients with right ventricular hypertrophy?
Effect estimate: r = 0.56-0.90
In patients with right ventricular hypertrophy, the right ventricle completes activation and repolarization later than the left ventricle, supporting the SI model of T wave generation.
Chen et al. (1991) conducted an observational in Chronic pulmonary thromboembolism and right ventricular hypertrophy. Computerized mapping and monophasic action potential recording was evaluated on Correlation between MAP90 and activation-recovery (A-R) intervals (r = 0.56-0.90). Computerized epicardial mapping in right ventricular hypertrophy revealed delayed right ventricular activation and repolarization, with significant correlations (r=0.56-0.90) between MAP90 and A-R intervals.
