Quiz

1. In the last echocardiogram on this page, the interventricular septum is flattened during diastole. What does this tell you?

2. In the second and fourth echocardiograms on this page you can see that the right ventricular chamber is larger than normal and that the right ventricular free wall is as thick as the left ventricular free wall (i.e., it is too thick). What is this characteristic of?
