Non-free Images[edit]

I changed the picture that was up for heartchambers because it is non-free. We can't use the adam images. I am having a hard time finding a good replacement for the heart valves image. That one has to go as well. It's such a shame we can't use the adam images. Great article by the way! Chaldor (talk) 21:06, 7 July 2008 (UTC)[reply]
I removed the heart valves images as well. We can't post it. Let's try to find a free alternative. Chaldor (talk) 21:25, 7 July 2008 (UTC)[reply]

Kentucky[edit]

I think S3 is Tennessee - TENN (S1) es (S2) see (S3) where as S4 is Ken (S4) TUC (S1) key (S2), as S1 is always the loudest. Anyone have a good resource to cite on this? 67.85.189.236 (talk) 22:28, 16 November 2008 (UTC)[reply]

To clarify, S1 is not always the loudest. It depends on where you listen to. S1 is the loudest when you're listening to the areas corresponding to the mitral or tricuspid areas since those are the areas that are closing for S1 (the closing of the valves makes the heart sound). Those areas would be the midclavicular line around the fourth or fifth ribs for the mitral area and around the 4th rib in the left sternal border for the tricuspid areas. In the aortic (2nd rib, right sternal border) and pulmonic (2nd rib, right sternal border) the S2 sounds are louder because the closing of the aortic and pulmonic valves is what creates the S2 sounds. To summarize, S1 (tricuspid/mitral closing) and S2 (pulmonic/aortic closing) relative volumes depend on whether you're listening over an area that corresponds to the the particular valve closing. Hope that makes sense.-- Bubbachuck (talk) 06:05, 28 April 2009 (UTC)[reply]

S3 is not always implying of pathology[edit]

S3 rarely associated with heart failure, whereas S4 is more signifying of heart failure. Specifically left ventricular hypertrophy. S3 is heard commonly during pregnancy and in a adults. — Preceding unsigned comment added by 71.180.67.53 (talk) 03:00, 25 February 2014 (UTC)[reply]
