Abstract

An improved pacemaker programmer and diagnostic system retrieves information stored within a pacemaker and analyzes the retrieved data in real time. The information stored within the pacemaker can be retrieved by means of a telemetry communication link. The system automatically identifies significant patient events (such as regions of increased heart rate, or loss of atrial or ventricular capture) and displays the significant events to the monitoring physician so that the physician is not required to scroll through the retrieved data to identify significant events. Furthermore, the system automatically suggests modifications to pacemaker parameters based upon certain retrieved data. The physician need only confirm the changes in order to modify the parameters within the pacemaker, so that the modification of pacemaker parameters is reduced to a "one step" process. The system also includes features for allowing the physician to interactively adjust program parameters while viewing the results of parameter changes in real-time.
