摘　　要：目的　调查中国健康人群心率的分布及其性别、年龄差异 ,评估传统的正常心率标准。方法　采集 5 36 0例 (男 36 14例 ,女 1746例 )健康人心电图 ,并按性别分为 5个年龄组 ,计算各年龄组心率的中位数、上限和下限值。结果　男性心率中位数为 6 7～ 6 8次 /min ,随年龄波动很小 ;女性心率的中位数为 6 7～ 73次 /min ,随年龄增长呈下降趋势。年轻女性心率的中位数、上限和下限值均比同年龄组男性快 5～ 6次 /min ,性别差异随年龄增长而减低或消失。 15 %的人群心率小于 6 0次 /min。男性心率下限值为 5 1次 /min ,而女性心率下限值 5 0岁以前约为 5 5次 /min ,5 0岁以后为 5 1次 /min。男、女心率上限值均随年龄增长逐渐降低 ,但在 5 0岁以后再次增快 ;总体人群的心率上限值为 95次 /min。Objective To investigate the normal heart rate limits in a Chinese population and to assess the traditional criteria of normal heart rate. Methods 5 360 (3 614 men and 1 746 women) healthy individuals were divided into five age groups: 18-29, 30-39, 40-49, 50-59 and ≥60 years. The electrocardiogram of each individual was recorded ,and their heart rate was measured by computer . The median, lower and upper limit heart rates were calculated, and the age and sex differences were examined. Results The median, lower and upper limit heart rates were 5-6 beats/min higher in young women than in young men. Fifteen percent (817/5 360) of the study population had a heart rate <60 beats/min, with a prevalence of 18% in men and 9% in women. The lower normal limit for men was close to 51 beats/min in all age groups, whereas women showed a decreasing trend from 55 to 51 beats/min with increasing age. The upper normal limits decreased with age for both sexes, while it increased again after the age of 50. The overall upper limit heart rate was 95 beats/min. Conclusion This study suggests that the traditional criteria for sinus tachycardia and bradycardia need adjustment when applied to a Chinese population.
