According to the classification of hypertension diagnosed in the older adult, hypertension that can be attributed to an underlying cause is termed a) secondary. Secondary hypertension may be caused by a tumor of the adrenal gland (e.g., pheochromacytoma). b) primary. Primary hypertension has no known underlying cause. c) essential. Essential hypertension has no known underlying cause. d) isolated systolic. Isolated systolic hypertension is demonstrated by readings in which the systolic pressure exceeds 140 mm Hg and the diastolic measurement is normal or near normal (less than 90 mm Hg).
