1. A pacing system comprising:
- an implantable pacemaker having means for sensing and recording heart rate/event data, means responsive to receipt of a download request signal for downloading the heart rate/event data to a remote receiver, and means for receiving the download request signal; and
an external programmer comprising;
means for generating the download request signal and sending it to the implantable pacemaker,means for receiving the heart rate/event data from the implantable pacemaker, andmeans for displaying the heart rate/event data in a multi-event bin heart rate histogram;
the multi-event bin heart rate histogram comprising a two-dimensional graphical chart of the heart rate/event data that shows;
(a) a multiplicity of heart rate zones arranged in order of increasing heart rate along a first axis, (b) a graphic representation of the number of heart rate events that occur within each heart rate zone, and (c) an indication of which events in each heart rate zone are sensed events, which are paced events, and which are premature events.

Abstract
Event/rate data gathered by an implantable pacemaker is displayed in a histogram format as a function of heart rate and event type, with multiple events being included in the display of each rate bin of the histogram. Event types include a paced event, a sensed event, or a premature ventricular event (PVE). Two types of histograms are provided: (1) a heart rate histogram that shows the occurrence of each event type in each heart rate bin as a function of the percent of total events in all heart rate bins; and (2) a histogram that shows event type distribution by rate bin.

27. A method of generating a multi-event bin heart rate histogram that depicts heart rate event data that has been sensed and recorded within an implantable pacemaker, the method comprising:
-
(a) retrieving the heart rate event data from the implantable pacemaker, (b) sorting the heart rate event data as a function of type of event and rate of event; (c) displaying the sorted heart rate event data in a multi-event heart rate histogram that comprises a graphical chart of the heart rate event data, wherein the graphical chart is made by; (1) providing a multiplicity of heart rate bins arranged in order of increasing heart rate along a first axis of the graphical chart, (2) creating a graphical representation of the number of heart rate events that occur within each heart rate bin, and (3) providing an indication of at least three types of heart rate events that occur within each heart rate bin. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)

35. An external programmer for use with an implantable pacemaker, the implantable pacemaker having means for sensing and recording heart rate event data, telemetry means for transferring the heart rate event data to the programmer, the external programmer comprising:
-
telemetry means for receiving the heart rate event data from the implantable pacemaker; and means for displaying the heart rate event data in a multi-event heart rate histogram as a function of heart rate zone, the multi-event heart rate histogram comprising a 100% stacked histogram, the histogram including; a plurality of heart rate bins arranged as a function of heart rate zone along a first axis; an indication of at least two types of heart rate events in each heart rate bin; and a display bar, extending from the first axis, that has a length that is representative of 100% of the number of heart rate events that have occurred within a respective heart rate zone, wherein the display bar of each heart rate zone is segmented into at least two portions corresponding to the at least two types of heart rate events; whereby the heart rate histogram provides a graphical indication of the heart rate event distribution by rate zone. - View Dependent Claims (36, 37, 38, 39, 40)
