II. Pathophysiology
- Abnormal flow in artery generates eddies
- Results in Arterial wall vibration
III. Causes
- Tortuous arteriosclerotic vessels
- Constricted arteries
- Congenital
- Intimal proliferation
- Arteriosclerotic Plaque
- Arterial aneurysm
- Thyroid artery dilatation
- Arteriovenous Fistula
- Aortic Coarctation with large collaterals
IV. Technique
- Auscultate with bell chest piece lightly held to skin
V. Signs
- Systolic Murmur auscultated over artery
- Thrill palpable over affected artery
