One of the few wiki pages I have ever seen that appears to be properly referenced (ie in proper academic style). Good job! Badgerpatrol 00:17, 2 February 2006 (UTC)

great page; I was impressed by the level of reference. One thing I did notice is that you refer to high-energy impacts throughout. I'm not sure if you agree, but I think it's important to note the difference between commotio and contusio cordis, which happens at higher energy levels. Garan et al (2005) described commotio cordis in pigs hit with baseballs travelling around 40mph, which equates to about 20J on the chest - depending on your frame of reference, this may not be high energy, especially as not all of it will reach the heart. Also, recent work by Cooper et al (2006) shows that, in a isolated guinea pig heart, impacts of 2-2.5J are required to avoid release of creatine kinase (a marker for cell damage). Perhaps you could take this into consideration if you are thinking about a re-write.

Just read the Maron / Mitten article and don't see slow response time at athletic events mentioned as receiving criminal prosecution. Was there another source or am I missing something?
I have altered the sentence which claims kids are more at risk because of their "fragile thoracic skeletons". I can find no evidence that it is the fragility of their bones that increases their risk, and rather think fragile bones would predispose against commotio cordis as it would make physical damage more likely.
I also wonder if it is more likely that kids are predominantly affected more because of the situations they put themselves in, rather than any mechanical properties?
Agreed that fragile is the wrong word to use, especially since kids skeletons are not more fragile. What they are is less calcified, and thus would put up less resistance to a blow, transferring more of the impact energy on to the heart. I'm not actually sure the sources say that though. --18.104.22.168 (talk) 14:54, 9 September 2013 (UTC)
Age as a Factor
Great page, but I am unsure why "Myocardial Contusion" redirects here, as it should have a page of its own since as the article states, it is a separate entity. Is it just that no-one has written a page for "Myocardial Contusion" yet? 26 February 2009 —Preceding unsigned comment added by 22.214.171.124 (talk) 02:18, 26 February 2009 (UTC)
"the total cardiac cycle has a duration of 1000 milliseconds (for a base cardiac frequency of 60 beats per minute)". Really? 1000 milliseconds. Could that be, wait for it, one second. But then, because we've not been condescending to the reader enough we clarify that one minute does in fact divide by sixty to produce one.
It is common practice to give all similar measurements in the same units. Since milliseconds is the appropriate units for the period of vulnerability (or indeed, discussing any particular event duration for heart rhythm), then its appropriate to continue using milliseconds for any other measurement related to that, such as the duration of one cycle. (The sixty seconds to a minute thing I didn't notice in a read through, but that does sound overly pedantic if it's still there). --126.96.36.199 (talk) 14:57, 9 September 2013 (UTC)
