Recording Heart Sounds
Using electronic stethoscopes, it is possible to record heart sounds via direct output to an external recording device, such as a laptop or MP3 recorder. The same connection can be used to listen to the previously-recorded auscultation through the stethoscope headphones, allowing for more detailed study of murmurs and other heart sounds, for general research as well as evaluation of a particular patient's condition.

Famous quotes containing the words recording, heart and/or sounds:
“He shall not die, by G—, cried my uncle Toby.
MThe ACCUSING SPIRIT which flew up to heaven’s chancery with the oath, blush’d as he gave it in;—and the RECORDING ANGEL as he wrote it down, dropp’d a tear upon the word, and blotted it out for ever.”
—Laurence Sterne (1713–1768)
“And at his heart there may have gnawed
Sick memories of a dead faith foiled and flawed”
—Edwin Arlington Robinson (1869–1935)
“While we were thus engaged in the twilight, we heard faintly, from far down the stream, what sounded like two strokes of a woodchopper’s axe, echoing dully through the grim solitude.... When we told Joe of this, he exclaimed, “By George, I’ll bet that was a moose! They make a noise like that.” These sounds affected us strangely, and by their very resemblance to a familiar one, where they probably had so different an origin, enhanced the impression of solitude and wildness.”
—Henry David Thoreau (1817–1862)
