RT Journal Article SR Electronic T1 Difference between upper and lower limb blood pressure in normal neonates using Doppler technique JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 734 OP 735 DO 10.1136/adc.49.9.734 VO 49 IS 9 A1 M. de Swiet A1 J. Peto A1 E. A. Shinebourne YR 1974 UL http://adc.bmj.com/content/49/9/734.abstract AB Using the Doppler technique, systolic upper limb blood pressure was found to be greater than lower limb blood pressure (mean difference 17 mmHg) in 20 normal neonates. Therefore, the finding of such a difference does not necessarily signify the presence of a pathological degree of coarctation of the aorta.
