- Abstract
Unlabelled: Transient episodes of apnea and bradycardia are common in preterm infants. Pronounced asystole or sinus arrest, however, is relatively rare and the clinical significance of such events is unknown., Objective: The purpose of our study was to: (1) evaluate the prevalence of severe bradycardic and asystolic events in infants studied with polygraphic cardiorespiratory monitoring, (2) characterize these events, and (3) correlate the events with other clinical findings., Methods: A total of 583 studies were performed in 454 preterm infants at a post-conceptional age 37.4 +/- 2.5 (range 34-42 weeks). Asystolic pauses were defined as no QRS complex for >or=3 s consistent with a heart rate <20 beats per minute (bpm). Severe bradycardia was defined as no QRS for >or=2 s consistent with a heart rate of 21-30 bpm., Results: Eight infants (29.5 +/- 3.9 weeks' gestational age, birth weight 1,283 +/- 445 g) met the criteria of having had at least 1 asystolic event (heart rate
