A comparison of digital and nondigital analysis of contraction records obtained from the nonpregnant uterus in vivo
article
A method is described to record on analogue and digital tape contractions obtained from the nonpregnant human uterus in vivo. A digital program is computed to calculate parameters comparative to: amplitude, interval, and duration of the contractions and active pressure area (APA) and linear displacement analysis (LDA) of 410 second segments of the records. Comparison of the results of the digital and of the conventional calculating method shows identical data as far as amplitude, interval, and duration of the contraction are concerned; results of APA and LDA with both methods differ to a large extent. Some difficulties in definitions and calculation procedures of the parameters of the contractions are discussed. © 1971.
