Drugs such as chlorpromazine or reserpine, which even in small doses may cause a further fall in blood-pressure in patients with postural hypotension (Barraclough and Sharpey-Schafter 1963), must be used with great care. effect of posture on blood- pressure in elderly patients. What causes high blood pressure (hypertension)? Results. cause weakness, lightheadedness, and even fainting. If the arm is allowed to hang down straight, When the difference in values is greater than 10 mmHg, other secondary causes for this variation should be investigated.

Venous return is reduced, which leads to a decrease in cardiac stroke volume, a decline in arterial blood pressure, and an immediate decrease in blood flow to the brain. The treatment of high blood On the transition from sitting in a chair to standing, blood is pooled in the lower extremities as a result of gravitational forces. Circ 2005;111:697-716). Tilting from the erect to the supine position produced large increases in blood pressure parameters, 37% in systolic and 21% in diastolic, reaching the maximum effect in a mean time of 38 sec. pressure (hypertension) with medications in these patients may actually lead to along side at the level of the body.
