Abstract

A method and system for analyzing and displaying pacing event data of an implantable pacemaker using a programmer device comprises downloading the pacing event data from the implantable pacemaker to the programmer device and processing the pacing event data to produce an Event Record. The Event Record includes actual pacing event data obtained and stored by the implantable pacemaker over a prescribed period of time as well as various statistical information derived therefrom. Selected parametric data of the Event Record are then displayed to the physician or other user on a display screen of the programmer device in a simple and comprehensible graphical format.
