Talk:Systole (medicine)

During atrial systole, the mitral and tricuspid valves are open. This article needs to be reviewed. It directly contradicts information stated in the mitral valve article.

Suggest further elaboration of article [Cardiac] [Systole] as a product of a set of ordered determinants. Systole is the sum of many moving pieces that drive blood forward. Concise mathematical description of these parameters in an encyclopedic media is a distinct challenge.

A. Systole as noted above has atrial and ventricular components.

  1. Atrial Systole
  2. Ventricular Systole

B. Time variations matched to valvular coaptation are helpful as well.

  1. Time Aortic/Pulmonary valves are open/time AV and PV valves are closed
  2. Time Tricuspid/Mitral valves are open/time closed

C. Mass variations in blood handling by the myocardium in a given heartbeat is an area historically well documented in encyclopedic references. Systole is perhaps best characterized mathematically in volumetric terms.

  1. Cardiac Output [Adolph Fick]
  2. Ejection Fraction=[ESV] End Systolic Volume/[EDV] End Diastolic Volume
     a. LVEF
     b. RVEF

D. Optimal myocardial perfusion with blood is a well documented determinant of systole.

  1. Unobstructed myocardial perfusion
  2. Myocardial vascular ischemia
     a. Macrovascular (large vessel) ischemia
     b. Microvasular (small vessel) ischemia

E. Optimal myocardial perfusion of electricity is yet another well documented determinant of Systole

  1. Sinotrial contribution
  2. Sympathetic outflow from the [autonomic nervous system] 

F. Mass variation of viable myocardium is also well documented but limited in teasing out dead muscle from performing muscle. —Preceding unsigned comment added by Lbeben (talk • contribs)

Article Assessment for WikiProject Medicine

Hello. I am a member of WikiProject Medicine, a Wikipedia wide project that maintains and improves articles that fall under the scope of medicine. Since your article has fallen under our scope, I have placed the correct template(s) on this talk page for verification. Upon reviewed of the article, I'd like to make a few points, as shown below:

• Assess article with class and importance factors
• Very well written, kudos to you!
• I would suggest a few more sources

Leave a message on my talk page if you have any questions. I'm glad this article could fall within our scope, and I hope to see it grow large! Many thanks! Renaissancee (talk) 21:21, 11 November 2009 (UTC)

Overly Technical

I don't have time to rewrite it, and perhaps not the expertise either, but I added a "Technical tag" because the introduction is unnecessarily complex. Davemcarlson (talk) 01:53, 10 February 2011 (UTC)

Left on right

Diagrams always depict the left ventricle and atrium on the right and the right side on the left. We should clear such a misunderstanding that the left side transports deoxygenated blood and vice versa. Could someone please label the diagram? — Preceding unsigned comment added by Caseyoon (talk • contribs) 13:31, 29 August 2013 (UTC)

Proposed merge

Should like to merge systole and diastole, and both into Cardiac cycle - most of entries are already covered in Cardiac cycle - it would be nice to see them both dealt comprehensively in Cardiac cycle where they could also be able to be viewed comparatively.
