The newborns' PMI is found in the left third to fourth intercostal space.The normal heart rate for infants who are not sleeping is 120 to 160 beats/min.However,a crying infant temporarily could have a heart rate of 180 beats/min.Heart murmurs during the first few days of life have no pathologic significance; an irregular heart rate past the first few hours should be evaluated further.Persistent tachycardia may indicate RDS; bradycardia may be a sign of congenital heart blockage.
