hypotension

 [hi″po-ten´shun]
diminished tension; lowered blood pressure. A consistently low blood pressure (systolic pressure less than 100 mm of mercury) usually is no cause for concern. In fact, low blood pressure often is associated with long life. However, extremely low blood pressure may be a sign of a serious condition such as shock, massive hemorrhage, hypovolemia, or severe dehydration from nausea and vomiting. In shock there is a disproportion between the blood volume and the capacity of the circulatory system, resulting in greatly reduced blood pressure. Hypotension may also be associated with addison's disease or inadequate thyroid function, but in both cases the primary disease produces so many other symptoms that the hypotension is not a major focus for concern.
orthostatic hypotension (postural hypotension) a fall in blood pressure (usually defined as a 20 to 30 point change in pulse or blood pressure), associated with dizziness, syncope, and blurred vision, occurring when a person goes from lying down or sitting to standing; it can be acquired or idiopathic, transient or chronic, and may occur alone or secondary to a disorder of the central nervous system such as the shy-drager syndrome.

postural hypotension

A drop in the blood pressure caused by standing or by rising suddenly. The brain is temporarily deprived of a full blood supply. This is a common cause of fainting.

The differential diagnosis between vasovagal, cardiogenic, and postural hypotension syncope is very important, because even in those patients with structural heart disease, vasovagal and postural hypotension have a better prognosis in terms of hospital readmission and death as a combined endpoint compared to cardiogenic syncope.
Multiple logistic regression model shows that patients with postural hypotension (OR = 68.657, p = 0.002), dementia (OR = 19.223, p = 0.002), broken skin (OR = 10.826, p = 0.001), and cerebral infarction (OR = 7.165, p = 0.011) are at a higher risk for foot drop development.

The major observation in this study is the regression of symptoms over the 4 years follow-up period: palpitations, postural hypotension, and paresthesia significantly decreased on the second examination, while on the third examination, statistically significant increase in frequency of palpitations and postural hypotension was found, however frequency of chest pain and paresthesia was statistically significant decreased.
This is known as orthostatic hypotension (postural hypotension); gravity reduces the rate of blood return from the body veins below the heart back to the heart, thus reducing stroke volume and cardiac output.
This is orthostatic or postural hypotension. In other words her blood pressure fell too low when she stood up and she came close to fainting.
