[edit] Hey

Hey, very usefull article, and I'm only a high school biology student so i felt weird editing this but it said "Yet even those these" and i changed it to "Yet, even though these" becuase it was the obvious intended meaning. 24.22.106.14 01:42, 9 December 2005 (UTC) Andrew McGuiness

[edit] Abnormal heart sounds

Would be useful to include a discussion about S3 and S4 heart sounds.

S3 is the sound of blood rushing into the ventricles during ventricular diastole, and S4 is the turbulence created during atrial systole. Both typically need to be recorded and possibly enchanced to discern specific diseases within the heart using the S3 and S4 heart sounds. Can anyone out there make that substantial enough to be encyclopedic?--Ryan! 04:12, 28 September 2006 (UTC)

Also, S3 is, according to Lilly's Pathophysiology of Heart Disease 4th ed., ch 2, p37, the result of tensing of the chordae tendineae during rapid filling and expansion of the ventricle. That seems much more specific (and plausible) than the explanation given about the "vibration of the ventricle and the surrounding structures." That brought to my view the entire ventricle vibrating, which is innacurate. Peetiemd 00:30, 3 October 2007 (UTC)

S3 is not the sound of rushing blood, which is descriptive of a murmur. As clearly shown in numerous recently published studies, S3 is caused by deceleration of early diastolic blood flow, resulting in a transfer of kinetic energy to the left ventricle and surrounding structures. The chordea tensing theory was discredited decades ago. S3 is a very low frequency sound, which suggests oscillation of a very large structure, certainly not chordae. The above comment stating that the entire ventricle vibrating as innacurate is misguided, likely by obsolete medical references.

S4 is not turbulence, but akin to the mechanism which produces S3, except the flow of S4 is powered by the atrial kick. —Preceding unsigned comment added by 76.17.202.79 (talk) 02:26, 22 February 2008 (UTC)

[edit] Soft versus Loud Murmurs

"soft murmurs are less likely to reflect a serious, if any, health problem; loud murmurs essentially always reflect a problem"

Can someone confirm this statement, I've always been taught otherwise. I was under the impression loudness gave no indication of the severity of the problem. 220.245.161.190 13:56, 26 July 2007 (UTC)

I will agree with you. I was taught that intensity of murmurs could not be used to differentiate severity of heart pathology. 75.187.51.238 02:11, 9 October 2007 (UTC)

Very small septal defects will cause very loud murmurs. Yet another reason why nobody should trust wikipedia for anything but fun browsing. —Preceding unsigned comment added by 92.232.46.19 (talk) 17:44, 11 June 2008 (UTC)

[edit] Notation

I think it would be helpful to have a section in here about doctors' notation, e.g. my notes say HS 1+2+0 which refers to heart sounds but am not entirely sure what this means. —Preceding unsigned comment added by 78.150.63.133 (talk) 17:08, 16 December 2007 (UTC)

[edit] S3 and S4 merge/split

Currently S3 and S4 are covered fairly extensively in two different articles, as a subsection of this heart sounds article and more extensively in gallop rhythm. They should be consolidated somehow, including these options:

  1. Split this info into separate articles for S3 (heart sound) and S4 (heart sound)
  2. Merge the gallop rhythm into this page
  3. Merge this page's subsection into gallop rhythm

Being somewhat of a separatist, I vote for (1), but I wanted to open it up to some debate before jumping in. Please opine. - Draeco (talk) 05:03, 30 April 2008 (UTC)
