Cardiovascular Physical Examination
1. What is the meaning of a slow rate of rise of the carotid arterial pulse?
2. What is the significance of a brisk carotid arterial upstroke?
Simultaneous emptying of the left ventricle into a high-pressure bed (the aorta) and a lower pressure bed: The latter can be the right ventricle (in patients with ventricular septal defect [VSD]) or the left atrium (in patients with mitral regurgitation [MR]). Both will allow a rapid left ventricular emptying, which, in turn, generates a brisk arterial upstroke. The pulse pressure, however, remains normal.
Hypertrophic cardiomyopathy (HCM): Despite its association with left ventricular obstruction, this disease is characterized by a brisk and bifid pulse, due to the hypertrophic ventricle and its delayed obstruction.
3. In addition to aortic regurgitation, which other processes cause rapid upstroke and widened pulse pressure?
Pulsus alternans is the alternation of strong and weak arterial pulses despite regular rate and rhythm. First described by Ludwig Traube in 1872, pulsus alternans is often associated with alternation of strong and feeble heart sounds (auscultatory alternans). Both indicate severe left ventricular dysfunction (from ischemia, hypertension, or valvular cardiomyopathy), with worse ejection fraction and higher pulmonary capillary pressure. Hence, they are often associated with an S3 gallop.
6. What is the Duroziez double murmur?
7. What is the carotid shudder?
8. What is the Corrigan pulse?
9. How do you auscultate for carotid bruits?
10. What is the correlation between symptomatic carotid bruit and high-grade stenosis?
11. What is central venous pressure (CVP)?
