目的:为了解不同时间、手臂、体位测量儿童血压、心率结果的差异,为儿童体检、临床及研究提供参考数据。方法:血压、心率均按统一标准进行测量。结果:上午与下午比较,舒张压均数下午高于上午,差异有统计学意义(t=2.77,P<0.01),卧位高于坐位,两者差异有统计学意义(t=3.13,P<0.01)。结论:确诊高血压时,建议在检查开始时同时测量两侧手臂,若在3次测量后收缩压差别>20mmHg(1mmHg=0.133kPa)或舒张压差别>10mmHg就须送心血管专科进一步检查,其时间和体位必须一致。
OBJECTIVE: To understand the difference of blood pressure and heart rate of children in different time, arm and position measurement and to provide reference data for physical examination, clinical and research of children. Methods: Blood pressure and heart rate were measured according to uniform standards. Results: The average diastolic pressure in the morning and afternoon was higher than that in the morning, the difference was statistically significant (t = 2.77, P <0.01). The supine position was higher than the sitting position, the difference was statistically significant (t = 3.13, P <0.01). Conclusions: When diagnosing hypertension, it is advisable to measure both arms at the beginning of the examination. If the systolic blood pressure difference is> 20mmHg (1mmHg = 0.133kPa) or the diastolic blood pressure difference is greater than 10mmHg after 3 measurements, the cardiological specialist should be sent for further examination. The time and posture must be the same.
