DESCRIPTION CONTINUED:  The majority of the recordings that have been made are from normal single pregnancies in order to establish normal ranges for important clinical parameters that have hitherto been unavailable. Recordings have also been made on a number of abnormal pregnancies. A number of abnormalities have been detected which were not known beforehand but subsequently confirmed by ultrasound. A case of Complete Heart Block was identified with the aid of the QinetiQ equipment that might otherwise have gone undetected. As a consequence the baby was delivered early and is doing well but otherwise might not have survived. Successful results have also been achieved for multiple pregnancies including twins and triplets in addition to singletons. This is believed to be a World First.
