972 the Qt Interval in Aborted Sids Infants

Abstract

i n 7 aborted SIOS i n f a n t s were performed during sleep i n the f i r s t four months o f l i f e . The QT index (QTc) was measured with an accuracy o f 2 msec o r b e t t e r . I n contrast t o recent suggestions, the mean QTc was s i g n i f i c a n t l y smaller i n the aborted SIDS than i n the normal i n f a n t s i n both REM and q u i e t sleep (p< 0.05, unpaired t -t e s t ) . Means SD are presented: NORMAL ABORTED SIDS

Spectral Analysis of Heart Variability in the Newborn Infant

“…Gordon et al [15] demonstrated enhancement of low frequency power in the spectral graphs of SIDS infants, as compared to their control group. On the other hand, some researchers have found no significant differences when analyzing heart rate variability [3,8].…”
