Frequency and timing of recurrent events in infants using home cardiorespiratory monitors☆,☆☆,★,★★

METHODS
We reviewed the records of all infants followed up in the Apnea Clinic at the Montreal Children's Hospital between September 1990 and December 1995. Three groups judged to be at increased risk for SIDS were defined: (1) Infants with apparent life-threatening events were defined according to the National Institutes of Health (NIH) Consensus Statement on Apnea of Infancy.8 They had received vigorous and prolonged stimulation, and sometimes mouth-to-mouth respiration and cardiac massage to
RESULTS
Between September 1990 and December 1995, 193 infants were discharged home with a monitor. An additional 9 infants (all siblings of children who had died of SIDS) were followed up, although the parents did not use a home monitor at any time. Of the 193 infants, 46 had a nonrecording monitor for either some part of or the whole recording period (14 ALTE, 30 SIDS siblings, 1 former premature infant, and 1 parental anxiety infant). These infants were followed up at a time when we had insufficient
DISCUSSION
The current study provides information on the natural history of apnea and bradycardia occurring in infants undergoing surveillance at home with cardiorespiratory monitors. In our study, subsequent significant events were recorded in 36% of these infants. The probability of having recurrent significant events at home was related to three factors. First, former premature infants were more likely to have events than infants with ALTE, SIDS siblings, or infants monitored for parental anxiety.
