## 해설

A strong, bounding carotid pulse in the neck (Corrigan's pulse) is a characteristic finding in aortic regurgitation. The carotid artery runs through the neck and can show exaggerated pulsations when there is significant backflow through an incompetent aortic valve.

## 임상 시나리오

Aortic Regurgitation (AR)
- Definition: Backward flow of blood from aorta into left ventricle
- Also called: Aortic insufficiency
- Key signs:
* Corrigan's pulse (water-hammer pulse)
* Wide pulse pressure
* Diastolic murmur
* Displaced point of maximal impulse (PMI)

Carotid Pulse Assessment
- Location: Lateral neck between larynx and sternocleidomastoid
- Normal characteristics: Regular, smooth, equal bilaterally
- Abnormal findings:
* Bounding pulse: AR, hyperdynamic states
* Weak pulse: Shock, stenosis
* Unequal pulses: Arterial obstruction

Clinical Manifestations of AR
- Early symptoms:
* Palpitations
* Dyspnea on exertion
* Fatigue
- Late symptoms:
* Orthopnea
* Paroxysmal nocturnal dyspnea
* Angina
* Heart failure symptoms

## 핵심 개념

- **carotid** — Either of the two major arteries, one on each side of the neck, that supply blood to the head and neck
- **jugular** — Any of several veins in the neck that drain blood from the head, brain, face and neck back toward the heart
- **temporal** — Relating to or situated in the temples of the head, specifically the arteries located on either side of the head
- **brachial** — The major blood vessel of the upper arm that continues from the axillary artery and branches into the radial and ulnar arteries
- **femoral** — The main artery of the thigh that carries blood to the lower limb, continuing from the external iliac artery
