目的探讨健康儿童24小时动态心电图的各年龄组正常窦性心率范围。方法收集自2001～2009年间在本院进行动态心电图检查的健康儿童128例(0.5～14岁)进行了24h动态心电图检测,观察各年龄组的昼夜最高和最低窦性心率及全天心搏总数、全天24h平均窦性心率的正常范围。结果显示正常窦性心率与年龄之间有明显的相关性,年龄越小心率越快,各年龄组之间心率的正常范围不同,并且差异有统计学意义(P<0.05),健康儿童24h动态心电图窦性心率的正常范围,因各年龄组之间存在差异,不能沿用及参考成年人动态心电图标准。
Objective To investigate the normal sinus heart rate range in each age group of healthy children with 24 hours ambulatory electrocardiogram. Methods 128 healthy children (0.5-14 years old) with dynamic electrocardiogram in our hospital from 2001 to 2009 were collected for 24-hour Holter monitoring. The highest and lowest sinus heart rate and total number of all-day heart rate 24h mean sinus heart rate throughout the normal range. The results showed that there was a significant correlation between normal sinus heart rate and age. The younger the age, the faster the heart rate, and the normal range of heart rate was different among all age groups. The difference was statistically significant (P <0.05) The normal range of ECG sinus heart rate, due to differences between the age groups, can not be used and reference adult Holter standards.
