Explain the term regional wall motion abnormality. Why do you think the abnormalities are "regional"?
What will be an ideal response?
A regional wall motion abnormality refers to an area of heart muscle that is contracting inadequately or not at all. The abnormality is caused by ischemia or infarction. Abnormalities may be limited to a specific region because regions of the heart are served by different coronary arteries. The ischemia or infarction would be due to a blockage in one arterial route but not all routes.
