摘要： An interactive medical information display system and method for displaying user-definable patient events is provided. The system includes a mechanism for acquiring physiological parameters from a patient and a mechanism for storing the parameters in a real-time database. In addition, the system includes a mechanism for users to define event types in an event defintion language and a mechanism for users to modify existing event types. Users then select a set of event types for display, and an event generator accesses the database to monitor the physiological parameters in order to detect event occurrences as defined by the event types. A display mechanism displays the event occurrences and provides users with the ability to select event occurrences randomly or sequentially. Upon selection, other information is displayed.

摘要： A pace pulse identification apparatus in which low frequency signals are rejected by a filter and the pace pulses and high frequency noise are applied to one input of a comparator. A threshold wave having an amplitude that is not significantly affected by pace pulses or spikes of noise is provided that has a minimum value when steady high frequency noise is absent and a value equal to the sum of the minimum value and a value that varies with the amplitude of high frequency noise when high frequency noise is present and which is applied to the other input of the comparator. The state of the comparator is changed when a pace pulse is present at the output of the filter because its amplitude exceeds that of the threshold wave.

摘要： Disclosed is a method and apparatus for discriminating pace pulse tails generated by signals discriminated from QRS complexes by mathematically ascertaining that the signal following the pace pulse peak has an exponential decay. The invention ascertains whether or not the waveform decays exponentially through application of a mathematical equation.

摘要： Apparatus for classifying QRS complexes as dual chamber paced, atrially paced or ventricularly paced by assigning complexes to groups in accordance with shape, deriving the intervals between pace pulses and their respective QRS complexes, determining if the intervals for a given number of recent complexes from the group to which the current QRS complex is assigned are clustered, and classifying the current QRS complex by the correlation between the intervals of its pace pulses and the intervals of said clusters.

摘要： Apparatus for effectively eliminating pace pulses from an ECG wave without introducing distortion comprising means for comparing the slope of the ECG wave with a threshold slope derived from the wave that is greater than the maximum slope produced in the wave by heart action and substituting values for a portion of the wave between first and second points on either side of the place in the wave where its slope exceeds the threshold value, the substituted values being interpolations of the value of the ECG wave occurring at said points. In a preferred embodiment means are provided for preventing the substitution from occurring unless a pace pulse is detected within a given distance of the said place in the ECG wave and means are also provided for setting said first point at a place in the ECG wave that occurs prior to a tail that precedes it.
