A job description is  a document that describes the general tasks, or functions, and responsibilities of a position. It may specify the functionary to whom the position reports, specifications such as the qualifications or skills needed by the person in the job, and a salary range.
If you have a blood pressure reading of 90/60 or lower, you're usually considered to have low blood pressure (also known as hypotension). Symptoms of low blood pressure include: 1  weakness. 2  fatigue. 3  dizziness. 4  feeling faint. 5  sweating. 6  nausea. 7  heart palpitations (if low blood pressure is caused by a heart problem).
Neurally mediated hypotension (NMH) occurs when the brain and heart don't communicate with each other properly. For example, when you stand for a long time, blood begins to pool in your legs. This causes your blood pressure to drop. In NMH, the body mistakenly tells the brain that blood pressure is high.
