体位性低血压(OH)是指从卧位转为立位3 min内,收缩压下降≥20 mmH g和(或)舒张压下降≥10 mmH g,伴或不伴各种低灌注症状的临床综合征。多次测量有1次达到上述标准即可诊断[1]。OH合并卧位高血压(SP)是老年人常见的临床症状,指有OH且卧位时收缩压≥140 mmH g和(或)舒张压≥90 mmH g。我科于2015年5月收治1例OH合并SP的老年患者,反复头晕发作,入院前跌倒1次,入院后测量卧位 Orthostatic hypotension (OH) refers to the change from supine to upright within 3 min, systolic blood pressure decreased ≥ 20 mmH g and / or diastolic blood pressure decreased ≥ 10 mmHg, with or without a variety of clinical symptoms of hypoperfusion Syndrome. Multiple measurements to achieve the above criteria can be diagnosed [1]. OH combined with supine hypotension (SP) is a common clinical symptom in the elderly, refers to the OH and supine systolic blood pressure ≥ 140 mmH g and (or) diastolic blood pressure ≥ 90 mmH g. Our department in May 2015 admitted to a case of OH combined with SP in elderly patients, repeated dizziness attack, fell down before admission 1, measured after supine
