不同年龄健康人群心率分析

ANALYSIS OF THE HEART RATES OF A HEALTHY POPULATION

对4023例从出生至79岁的不同年龄正常人群心率进行了分析。以年龄分组的最少组数，定出不同年龄阶段的正常心率范围。根据研究结果，认为在成人方面，以往规定正常心率60～100次／min，两边数据都偏高。正常成人心率最好规定在55－90次／min或55～95次／min，这样可避免将正常心率误诊为窦性心动过缓或将窦性心动过速误作正常心率。在儿童和成人中，女性心率＞男性，一般相差约为2～7次／min。

The heart rates of 4, 023 healthy individuals ranging from infants to adults under 80 years old were analysed.The normal heart rate range of different ages was provided by the fcwest number of age groups. According to the re-search results, the authors found that the previous upper and lower limits of normal heart rate, 60~ 100 bpm, were too broad for adults. It is preferable to use 55 ~ 90 bpm or 55 ~ 95 bpm as the normal heart rate ranged for adults.Thus, inadequate diagnoses of sinus bradycardia and sinus tachycardia in adults can be avoided. The heart rates of both sexes are different in adults and chi1dren. The heart rate are faster in fcmales than in maIes, with a difference of 2 ~ 7 bpm.
