## 문제

The patient's heart demonstrates ______ motion on the apical segment, indicating ventricular aneurysm formation.

## 보기

1. dyskinetic **✔ 정답**
2. akinetic
3. hypokinetic
4. hyperkinetic
5. normal

**정답: 1**

## 해설

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.

## 임상 시나리오

Wall Motion Abnormalities:

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

5. Assessment Methods:
- Echocardiography
- Cardiac MRI
- Left ventriculography
- Regional wall motion scoring

6. Clinical Significance:
- Diagnostic tool for MI
- Prognostic indicator
- Guide for treatment decisions
- Risk assessment

## 핵심 개념

- **dyskinetic** — Abnormal movement where a segment moves in the opposite or paradoxical direction from what is expected during contraction
- **akinetic** — Complete absence of movement or motion in a segment of tissue
- **hypokinetic** — Reduced or decreased movement compared to normal motion
- **hyperkinetic** — Increased or excessive movement compared to normal motion
- **normal** — Regular or expected pattern of movement without any abnormality
