what constitutes bradycardia
Bradycardia means a slower than normal heart rhythm. In newborns, a heart rate is termed bradycardia if it falls below 100 beats per minute in a baby less than 1250 g (2 lb 12 oz) or to less than 80 beats per minute in a bigger baby. When babies are in the NICU, their hearts are monitored, and episodes of bradycardia are treated with stimulation.
