The authors showed that switching from endocardial to epicardial pacing resulted in a change of activation sequence between epicardium and endocardium, which was associated with an increase in QT ...

In this disorder, echocardiography demonstrates a thin epicardium with extremely hypertrophied endocardium and prominent trabeculations with deep recesses. These features tend to be apically localized ...

The right ventricular wall is very thin and hypocontractile. The endocardium essentially connects directly to the epicardium without the muscle layer in between. The treatment is surgical repair ...
