Perinatal arrhythmias may occur either during fetal life or in the early neonatal period. These arrhythmias include both tachycardias and bradycardias. This article presents a brief overview of fetal and neonatal arrhythmias concentrating on their presentation, diagnosis, and treatment.
OBJECTIVE: The purpose of this investigation was to investigate, in high-risk infants, the occurrence of abnormalities in documented monitor downloads during the side versus prone position. STUDY DESIGN: Forty infants admitted to the A. I. duPont Hospital for Children with diagnoses associated with sudden infant death syndrome were included in this investigation. During an overnight hospitalization, infants were placed on home apnea monitors, with computer memory to capture alarms for apnea > 20 seconds, age-defined bradycardia, and tachycardia. Infants were studied for 12 hours. Each infant was assigned to 6 hours of prone and side during the 12-hour period, with order of position randomly assigned by random number generation. Differences between the two positions in alarm frequency and significant events, as determined by a blinded interpreting physician were analyzed by Fisher exact test, with p < 0.05. Power analysis necessitated 20 patients in each group, with beta error of 0.2. RESULTS: Eleven episodes of apnea occurred in the prone position, and 16 in the side position (p = NS). The mean numbers of apnea events per tracing in the prone position was 0.27 +/- 0.84 and 0.39 +/- 1.1 in the side position (p = 0.58). The mean number of bradycardia events per tracing in the prone position was 0.44 +/- 1.45 and 0.49 +/- 1.94 in the side position (p = 0.9). CONCLUSION: Clinicians need to be cautious when recommending the side or prone position in this group of high-risk infants. The results in this investigation provide support for the Back to Sleep Campaign recommendations to be applied, not only to healthy term infants, but higher risk infants as well. Studies of the high-risk infant in the supine position are warranted.
A variety of symptoms that accompany migraine in the child and adult are mediated by the autonomic nervous system. Significant effects on cardiac rhythm are uncommon, but can be life threatening. We describe a 3-year-old girl in whom migraine-associated vomiting precipitated cardiac asystole which was effectively treated with a cardiac pacemaker.
