bradycardia of prematurity
Episodes of abnormally slow heart rate common in premature infants, often accompanied by apnea and desaturation.
Full Definition
Bradycardia of prematurity refers to episodes of heart rate below 80-100 beats per minute in preterm infants, typically occurring as part of the apnea-bradycardia-desaturation triad. This condition is caused by immature autonomic nervous system control and respiratory center development. Episodes may be spontaneous or triggered by stimulation, feeding, or positioning. Bradycardic events are concerning because they can lead to decreased cardiac output and tissue hypoxia. Treatment may include caffeine citrate therapy, gentle stimulation, or in severe cases, bag-mask ventilation to restore normal heart rate and oxygenation.
Usage
Usage note: Document frequency, duration, and interventions required. Often occurs with apnea and should be reported as part of the triad.
