Hypertension (HTN or HT), also known as high blood pressure or arterial hypertension, is a chronic medical condition in which the blood pressure in the arteries is persistently elevated.ulse pressure (the difference between systolic and diastolic blood pressure) is frequently increased in older people with hypertension.

In chemistry, a hydron is the general name for a cationic form of atomic hydrogen, represented with the symbol H+ . The term proton refers to the cation of protium, the most common isotope of hydrogen.nlike other ions, the hydron consists only of a bare atomic nucleus. The hydron (a completely free or naked hydrogen atomic nucleus) is too reactive to occur in many liquids, even though it is sometimes visualized to do so by students of chemistry.
