A method and apparatus for implementing a user interface for displaying uterine contraction information is provided. The contraction signal is processed to derive a sequence of contraction persistence indices. Each contraction persistence index in the sequence is associated to a portion of the contraction signal and conveys whether there is an excess in the rate of contraction in the associated portion of the contraction signal. If there is an excess in the rate of contraction in the associated portion of the contraction signal, the contraction persistence index conveys whether this excess is part of a sustained pattern of excess in the rate of contractions or whether the excess is likely to be transient. The sequence of contraction persistence indices is displayed to a user. Optionally, the graphical user interface is adapted for selectively causing an alarm event based at least in part on the sequence of contractility persistence indices. The method and apparatus may be implemented on any suitable computing platform such as for example desktop computers, laptop computers and personal digital assistants (PDAs).
