Standard electrocardiogram recordings were performed on a total of 7254 newly born infants from two maternity hospitals. Fifteen recordings were obtained on 15 infants who subsequently suffered sudden infant death syndrome. None showed lengthening of QT intervals sufficient to warrant the description of 'long QT syndrome'. When the QT intervals corrected for heart rate of cases with sudden infant death syndrome were compared with controls in age matched groups or after individual matching for postnatal age, hospital of birth, and weight at birth, no significant differences could be identified.
对来自两家妇产医院的7254名新生儿进行了标准心电图记录。对随后患婴儿猝死综合征的15名婴儿进行了15次记录。没有一份记录显示QT间期延长到足以被描述为“长QT综合征”。将婴儿猝死综合征病例经心率校正后的QT间期与年龄匹配组的对照组或根据出生后年龄、出生医院和出生体重进行个体匹配后的对照组进行比较,未发现显著差异。
