Dyskinetic motion, where a segment of the heart wall moves in the opposite direction during systole, is characteristic of ventricular aneurysm formation. This abnormal movement pattern indicates severe myocardial damage with scar tissue formation.
1. Dyskinetic: Paradoxical outward movement during systole
- Associated with ventricular aneurysm
- Indicates severe myocardial damage
- Common after transmural MI
2. Akinetic: No movement during systole
- Complete loss of contractility
- Often seen in scarred myocardium
- Indicates severe wall damage
3. Hypokinetic: Reduced movement during systole
- Decreased contractility
- May indicate ischemia
- Partial myocardial dysfunction
4. Hyperkinetic: Increased movement during systole
- Compensatory mechanism
- Often seen in adjacent segments
- Response to reduced function elsewhere
