This 18 minute video from the University of Virginia is one of the most thorough videos on the cardiac exam. It allows a close-up observation of a cardiac exam, including how to interpret pulses, inspect, palpate, auscultate the chest, and verbal instruction on how to listen to different heart sounds (although it does not include actual heart sounds). The physician in the video is very thorough and explains each step and the purpose behind it. Video quality is quite good. Quicktime and high-speed internet connection required.
