Visual assessment of regional wall motion (left ventricle)
| TYPE OF MOTION | DEFINITION | WALL MOTION SCORE |
| Normal | Normal thickening (typically >30% thickening from end-diastole to end-systole). | 1 |
| Hypokinesia | Reduced thickening (typically 10–30% thickening from end-diastole to end-systole) | 2 |
| Akinesia | Markedly reduced, or no thickening (<10%) | 3 |
| Dyskinesia | Paradoxical thinning and/or outward directed motion during systole | 4 |
| Aneurysmatic | Diastolic deformation | 5 |
