해설
Dyskinetic movement refers to paradoxical wall motion where a segment of the heart moves in the opposite direction to normal during contraction. This abnormal motion typically indicates scarred or severely damaged heart muscle, often seen after myocardial infarction.
1. Dyskinetic: Paradoxical outward movement during systole
2. Hypokinetic: Reduced wall motion
3. Akinetic: No wall motion
4. Hyperkinetic: Increased wall motion
5. Dyssynchronous: Uncoordinated wall motion
Clinical Significance:
- Seen on echocardiogram
- Common after myocardial infarction
- Indicates myocardial damage/scarring
- Affects ejection fraction
- May lead to heart failure
Assessment Methods:
- Echocardiography
- Cardiac MRI
- Left ventriculography
- Wall motion score index (WMSI)
dyskinetic — Abnormal movement where a segment moves in the opposite direction to normal during contraction, typically indicating scarred or damaged heart tissue
hypokinetic — Reduced or decreased movement of a segment compared to normal contractile function
akinetic — Complete absence of movement or contractile function in a segment of heart muscle
hyperkinetic — Increased or excessive movement compared to normal contractile function
asynchronous — Uncoordinated movement where different segments contract at different times rather than simultaneously
