Blood pressure variability(BPV) is one of the physiological features of blood pressure (BP), and it is an index used to describe the fluctuation BP in a period of time .The abnormal fluctuation in BP or abnormal in-crease in BPV can cause damage to the heart ,brain,kidney and carotid artery etc , and has impact on overall prognosis of the patients with hypertension .To recognize BPV and its damage to the target organs should be a great help to the prevention of the target organs damaged in the patients with hypertension and improve their quality of life and the prognosis.In this paper,the methods of analysis and monitoring of BPV ,and the relationship between BPV and target organ damage in patients with hypertension were briefly reviewed .%血压变异性（ BPV）是人类血压（ BP）的最基本的生理特征之一，是反映一段时间内BP波动的指标。 BP的异常波动，BPV增大可导致心、脑、肾及颈动脉等重要靶器官的损害并对总体预后产生影响。认识BPV及其靶器官损害，有助于对高血压患者靶器官损害的防治，从而提高患者的生活质量，改善预后。该文对BPV的分析和监测方法，以及BPV与靶器官损害的关系研究进展作简要的综述。
