Data derived from detailed studies of normal phrenic nerve latency in a large group of children are presented. They highlight the major differences between the three previously published studies of normal children. Phrenic nerve latency shows a curvilinear relationship with age, averaging 6.0 ms at 0-6 months, falling to 4.8 ms between 1 and 2 years, then rising to 6.3 ms between 10 and 18 years of age. These data represent the largest published study on normal phrenic nerve latency in children. (C) 2001 John Wiley & Sons, Inc.
