The Authors describe their experience in telephonic transmission of cardiotocographic recordings. With a Corometrics 116 and 410 unit installed in a remote facility, 61 CTG recordings were tele-transmitted and received by a Toshiba personal computer. The concordance between original and transmitted CTG record was excellent and a very low percentage of signal loss during transmission (3.2%) was found. The advantages of telephone transmission of CTG in peripheral areas are stressed.
