Talk:Human heart

possible inconsistency between the figures in the "Structure" and "Functioning" sections

There seems to be an inconsistency between the figure in the "Structure" section and the one in the "Functioning" section. One indicates that the left lung is on the right hand side of the figure, while the other seems to indicate the opposite. 212.178.200.72 (talk) 07:41, 26 July 2010 (UTC)Pedro Martinez

How does exercise affect the heart?

Can someone add information to this article about how exercise, whether moderate or intensive, short-term or long-term, affects the heart positively or negatively, and for how long? For example, if someone were to exercise at 80% or above of their fastest possible heart rate, especially for a long period of time every day, would it lead to the heart being temporarily or permanently damaged? If so, what kind of damage would occur, why would the damage occur, and how long would it take for it to heal? Wsmss (talk) 22:24, 18 January 2011 (UTC)your talk

Heartbeat Hypothesis

Is the heartbeat hypothesis true? Do hearts have a limited number of heartbeats? If so, does it mean that if you exercise, you'll be reducing the lifespan of your heart since you're using up more heartbeats? Wsmss (talk) 15:03, 15 August 2011 (UTC)

Please read Heartbeat hypothesis that gives an outline of the idea, even though I have some objections (which you can read on the talk page).Sjö (talk) 20:21, 7 November 2011 (UTC)

Structure section

I'm not sure if this is correct but the sentence "The double membrane of pericardium consist of the pericardial fluid which nourishes the heart and prevents heart from shocks" doesn't seem to be right. Terminal Shift (talk) 05:58, 12 October 2011 (UTC)

Anatomy of the heart

Surely there should be more on the location of the heart in the body, its relations to e.g. the lungs and diaphragm, its innervation by the vagus etc? Innervation particularly seems to be lacking. Td1wk (talk) 15:58, 14 May 2012

Right or Left of body?

All I wanted to know was if the heart is on the right or left of the body. Pretty basic question, but the article doesn't say, and the picture has it situated right in the middle. Guess this relates to the comment above. (Looked it up, apparently it's pretty much central but a little to the left)

File:Heart diagram-en.svg to appear as POTD

Hello! This is a note to let the editors of this article know that File:Heart diagram-en.svg will be appearing as picture of the day on May 28, 2013. You can view and edit the POTD blurb at Template:POTD/2013-05-28. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. Thanks! — Crisco 1492 (talk) 10:48, 12 May 2013 (UTC)

New heart images from Blausen

Hi all, I recently helped to upload a donation of 20 heart-related illustrations by Blausen Medical (see commons:Category:Images from Blausen Medical Communications). I've been inserting them into articles. The images below seem particularly suited for this article, but it already has many images so I wasn't sure where to put them. Do you think these are useful, and if so could you help me insert them? Thank you! Dcoetzee 08:45, 1 July 2013 (UTC)

The heart as an endocrine organ?

Surprised to see no mention in the article of the heart not just as a simple "pump" but as an endocrine organ, as per these articles http://ajpheart.physiology.org/content/301/1/H12 and https://www.ncbi.nlm.nih.gov/pubmed/23248059 Could someone enlighten me as to what the current thinking is on this subject? --Brian Fenton (talk) 13:27, 22 November 2013 (UTC)

Proposed merge with Heart valve

The following discussion is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.

Am proposing these four merges because:

• I feel it is unnecessary to fragment this topic into these four separate articles
• This is a disservice to readers, making the content much harder to read by unnecessarily displaying it on so many different articles.
• Articles on the individual ventricles, valves and atria already exists, and there isn't really anything that a separate article could portray that isn't covered in the general heart article or the individual articles
• In fact there is significant duplication of content and fragmentation of editing that this has resulted in no articles of high quality. This would be improved if the articles were consolidated in an effective way into one article.
• The articles, if necessary, could be re-expanded at a later date LT910001 (talk) 05:08, 19 March 2014 (UTC)

Support for merges - these topics would be much better treated as subcategories. Iztwoz (talk) 14:30, 6 April 2014 (UTC)

Having considered this for a couple of weeks, I don't see how these mergers could be performed without creating an article that is very complicated and difficult to read. I'm withdrawing this merge, and proposing a smaller subset of mergers at Talk:Heart chamber. --LT910001 (talk) 23:19, 6 April 2014 (UTC)

Proposed merge with Right heart

This article is unnecessary and could easily be covered (if it is not covered already) in the function or clinical signifiance sections of this article. Having further fragmentation is confusing to readers and means it is harder to access content. LT910001 (talk) 00:33, 3 April 2014 (UTC)

See above. --LT910001 (talk) 23:19, 6 April 2014 (UTC)
