title: Doppler evaluation of normalized peak filling rate in early neonatal period.
abstract: In conclusion, the NPFR value did not change during the early neonatal period. The fact that this index does not change suggests that it might be useful as a parameter for diastolic filling, assuming that there is no significant diastolic filling change in the left ventricle over this time frame.
