Hypotension is a condition in which the pressure in the body's circulating arteries is below normal.Hypotension is generally considered to be lower than 12/8kpa (90/60mmHg) in the upper limb arteries of adults.It can be divided into physiological and pathological hypotension according to etiology, and acute and chronic hypotension according to the form of onset.Postural hypotension is a type of chronic hypotension. The occurrence of hypotension in some patients is related to postural changes (especially in the upright position), which is called postural hypotension. postural hypotension was defined as a drop in systolic blood pressure >20mmHg or diastolic blood pressure >10mmHg within 3 minutes of changing position to upright, accompanied by hypoperfusion symptoms, including dizziness, dizziness, blurred vision, fatigue, nausea, cognitive dysfunction, palpitations, and neck and back pain.The World Health Organization also has a clear standard for the diagnosis of hypertension, but there is no unified standard for the diagnosis of hypotension. Acupuncture and moxibustion has been accepted by more and more patients and medical staff at home and abroad because of its high safety and accurate efficacy. this study is to through the acupuncture treatment of orthostatic hypotension randomised controlled trials (RCTs randomisedcontrolledtrials) and Meta analysis study of quality, evaluate the related curative effect in order to make up for the defect of relevant clinical evidence.
