******** I think Supraventricular Extrasystole should maybe put under PREMATURE ATRIAL CONTRACTION and not have its own page but dont know for sure
Supraventricular Extrasystole
editA supraventrocular extrasystole is an extrasystole or premature electrical impulse in the heart, generated above the level of the ventricle[1]. This occurs when the extra impulse is conducted not only to the ventricle but back to the SA node. This disrupts the depolarization, causing a shift in the sinus rhythm as cardiac activity can only occur after a normal sinus interval[2][3]. The mechanism behind a supraventricualr extrasystole causes a compensatory pause to be observed[1]. When observed in healthy patients, the irregular rhythm is harmless. However, frequent occurrences of the supraventricular extrasystole can be seen in cases with inflammation of the mydocardium, lack of oxygen, hypokalemia, digitalis intoxication, neurovegetative dysfunctions or overextend atrial walls[2].
Electrocardiogram
editThe premature impulse associated with supraventricular extrasystole has a an extra heart contraction and an extra premature QRS complex. Normal thin appearance, proceeded by P wave, incomplete compensatory pause.[4]

Evaluation of Physiology Wikipedia Articles:
In the history section of this article the information about each element having a corresponding humor (black bile, yellow bile, blood and phlegm), cell theory and the development of the Physiological Society should be cited. Also in the history section, the information on Ivan Pavlov and his work on conditioned reflexes distracted me as to me it falls under a more psychological branch and did not seem relevant in terms of the history of physiology. Many areas of the women in physiology section need to be properly cited as well. In the human physiology section, all the information on homeostasis, and the endocrine and nervous system need citations. In terms of covering the topic of physiology as a whole the article seems to overrepresent the history and underrepresent the actual topic of physiology itself. After clicking on a couple of the citations, the sources appear to be reliable and non-bias but the article does have areas of close paraphrasing that match some of the citations almost word for word. Overall, I found the article pretty poorly written as there not only a significant lack of citations but also seemed to be missing some content as mainly only history/ significant figures were emphasized.
Week 4: Thinking about sources and plagiarism:
Blog posts and press releases are often poor sources of information because they usually contain large amounts of bias. Something like a blog post is usually unregulated and therefore anyone can be posting information without reliability and the information is often written in a way to sway the viewer towards one side of an argument. Press release information and blog posts are not written to solely contain factual information but to convey whatever message the author wants to get across. A company's website is also a poor source because the website will only portray the company in a positive manner and therefore the whole story will not be complete, if there are any issues or failures within the company, the website will not disclose that information. Copy right violation is using information that you do not have permission to use as the source has claimed it solely as their own while plagiarism is directly copying information use have permission to use but instead of using the information you are simply stealing the the author's words. To avoid plagiarism and close paraphrasing to best thing to do would be to read the article once or twice and then write out what you took away from the article without looking at the sources that way you make sure you are only using the information/ broad ideas and not copying the actual content.
For my project, I am working with Allison on the article Supraventricular extrasytole. This article is classified as a stub article, and it contains zero sources with a lot of information that needs to be added to. The page also contains the suggestion to merge the article with premature atrial contraction so I will be looking at sources for information on that topic as well. The sources I am looking for will need to contain information on the prognosis, treatment, symptoms, etiology, etc. on the disease. The sources I have found thus far are:
https://www.ncbi.nlm.nih.gov/pubmed/23499279
http://onlinelibrary.wiley.com/doi/10.1111/j.0954-6820.1949.tb06927.x/abstract

Week 5: The article has the beginning of a strong lead but still needs to be worked on. From there, the article requires a lot of work to be done with the addition of sections on ECG, prognosis, treatment, symptoms, etiology. Also because the disease is largely based on malfunctioning of the action potential , the article may be improved with additional information on the workings of the action potential (Na+ gates, etc.)
