窒息新生儿21例(Apgar评分1分钟≤6分),对照组为健康新生儿30例.窒息组复苏后入婴儿室,对照组入婴儿室后即开始做24小时Holter心电图.结果窒息儿组最快心率(184.86±13.14)明显高于对照组(173.83±10.09),窒息组最慢心率(75.24±4.92),平均慢心率(82.81±6.95)及24小时心搏总数(158251±9233)均明显低于对照组(90.47±5.69,99.47±6.40,178865±10876),以 Asphyxial neonates in 21 cases (Apgar score 1 minute ≤ 6 points), the control group of 30 healthy newborns .Asphyxial group after resuscitation into the baby room, control group into the baby room 24 hours after Holter electrocardiogram .Results Asphyxia group The fastest heart rate (184.86 ± 13.14) was significantly higher than that of the control group (173.83 ± 10.09), the slowest rate of asphyxia group (75.24 ± 4.92), mean slow heart rate (82.81 ± 6.95) and total 24-hour heart rate (158251 ± 9233) Significantly lower than the control group (90.47 ± 5.69,99.47 ± 6.40,178865 ± 10876), with
