Abstract

A system and method for the dynamic display of scatter-plot data uses a color monitor or gray-scale monitor to indicate the relative frequency of occurrences of interval pairs corresponding to the scatter-plot data. A variety of user selectable analysis and display parameters are available to select the type of data desired for the scatter-plot display. The user selectable parameters include time parameters that allow the user to review all scatter-plot data collected over a first period of time in smaller increments of time. The system can display different time increments in different colors or intensities. The system also permits the selection of a particular interval pair and display the raw data corresponding to the selected interval pair. If there is more than one occurrence of the selected interval pair, the system permits the user to select from the plurality of occurrences and displays the raw data associated with the selected occurrence. If the system uses cardiac data, the user can specify analysis parameters that include the selection of beat source for each interval in the interval pair, clinical labels corresponding to cardiac rhythms, and pacemaker or intrinsically generated heartbeats. The interval pair may be derived from three successive heartbeats. The system can scan through a data file collected over a period of time. The display can show new interval pairs in one color or intensity and older interval pairs in other colors or intensities to provide a fading action in the display.
