Task: Answer Verification
Input (English): Question: Does cardiac myocyte transplantation increase global epicardial repolarization heterogeneity in a rat infarct model?
Answer: Both fetal cardiomyocyte engraftment in the normal myocardium and coronary ligation increased repolarization heterogeneity. However, fetal cardiomyocyte engraftment in an infarcted region did not further increase repolarization heterogeneity.
Output (English): no
