External links modified
Hello fellow Wikipedians,

I have just modified 1 one external link on Pathophysiology of hypertension. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
 * Added archive http://www.webcitation.org/5kGLMdqnn to http://www.cvphysiology.com/Blood%20Pressure/BP006.htm

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at ).

Alternative definition of primary/idiopathic/essential hypertension and its sodium/potassium ratio etiology
The current statement at the end of the first paragraph:

"The pathophysiology of essential hypertension remains an area of active research, with many theories that are not mutually exclusive."

is unsupported by references, so I removed it. The statement:

"Essential hypertension indicates that no specific medical cause can be found to explain the hypertension." is likewise not supported by references, and reflects one of the definitions found in the literature. So I altered the text to indicate this and added a section on the sodium/potassium ratio etiological hypothesis of essential/primary/idiopathic hypertension, with a reference to epidemiological research which supports this. I made similar changes to the Pathophysiology section of the main Hypertension article. Ideally I would update the article on essential hypertension too. The whole notion of "primary" hypertension having no known cause, and then of discussing causes, which is hardly any different from pathophysiology, seems confusing to me, but has an historical basis. However, if some researchers demonstrate convincingly that they have an explanation for this majority of hypertension cases, then the "unexplained" definition should no longer apply.
