Abstract
A system for monitoring the operation of a cardiac pacemaker and the response of the patient to the pacemaker includes an ARRHYTHMIAGRAPH that displays the occurrence of pacemaker signals in relation to overall QRS cycles and analyses the relationship of pacemaker signals to QRS cycles. A predetermined set of values are used to compare against measured QRS and pacemaker values. The result of the comparison is a determination of whether a QRS was initiated by a pacemaker signal. This determination is conveyed to display means where an ARRHYTHMIAGRAPH is used to illustrate the result in a visually discernible manner.
