|Heart Sounds Tutorial:|
|This online program focuses on the four common valvar lesions in the left heart: aortic regurgitation, aortic stenosis, mitral regurgitation, and mitral stenosis. Actual patients illustrate the physical findings associated valvar disease. You can listen to the patient's heart at several listening locations, while at the same time you can see video of pulsations in the neck, precordium, or extremities. The findings are explained with text, as well as illustrated with phonocardiograms, hemodynamic data, and computer animations.|
|Heart Sounds Quiz:|
|This interactive quiz will test your ability to identify correctly the first and second heart sounds, extra sounds, diastolic and|
systolic murmurs in recordings of actual patients, using a computer animation of the carotid pulse for timing.
|High- and low-frequency sounds illustrated:|
|This brief program demonstrates the difference between events that cause low frequency sounds (e.g., a third heart sound)|
and events that cause high frequency sounds (e.g., an ejection click).
|Physiological splitting of the |
second heart sound:
