Abstract

A physician'"'"'s programmer for an implantable device is disclosed. The programmer includes a receiver for receiving wireless transmission data from the implantable heart monitor. A processor is configured to extract from the wireless transmission data ST-deviation histogram data as a function of heart rate. The histogram data for a particular heart rate range is shown on a display in the form of a bar chart. The histogram data for a plurality of heart rate ranges is shown in the form of a chart with multiple line plots.

Claims

1. A device for displaying ST-segment voltage data collected by an implantable heart monitor, comprising:

a receiver adapted to receive wireless transmission data from the implantable heart monitor, wherein the wireless transmission data include histogram data pertaining to ST-segment voltage values;

a processor configured to;

(a) extract ST-segment voltage values from the wireless transmission data and calculate therefrom an ST deviation value for each heart beat within a predetermined time interval;

(b) create a plurality of histograms, each of said histograms associated with a specific heart rate range, each of said histograms being taken over said predetermined time interval; and

(c) display a specific histogram associated with a specified heart rate range where the ST deviation value is displayed as a function of the total number of beats measured within said specified heart range, the histogram being displayed in the form of a bar chart such that ST-segment voltage ranges appear on a horizontal axis and that beat counts appear on a vertical axis.

2. A device for displaying ST-segment voltage data collected by an implantable heart monitor, comprising:

a receiver adapted to receive wireless transmission data from the implantable heart monitor, wherein the wireless transmission data include histogram data pertaining to ST-segment voltage values;

a processor configured to;

(a) extract ST-segment voltage values from the wireless transmission data and calculate therefrom an ST deviation value for each heart beat within a predetermined time interval;

(b) create a plurality of histograms, each of said histograms associated with a specific heart rate range, each of said histograms being taken over said predetermined time interval; and

(c) display a specific histogram associated with a specified heart rate range where the ST deviation value is displayed as a function of the total number of beats measured within said specified heart range, the histograms being displayed in the form of a corresponding plurality of line plots such that ST-segment voltage ranges appear on a horizontal axis and that beat counts appear on a vertical axis.
