What is inferior ischemia?

Inferior WALL?? Could this be inferior wall ischemia? If so, this refers to the inferior wall of the heart, i.e. Location (bottom) of the ischemia. Ischemia indicates a lack of blood and therefore oxygen & nutrients to any part of the body, in this case the bottom of the heart.
Lack of blood flow. By inferior, i suppose you mean inferior wall ischemia... Which would be decreased blood flow to the inferior wall of your heart.
