Method and system for displaying patient activity data using Poincaré and intensity plot
First Claim
1. A system for displaying patient activity data, comprising:
- an implantable cardiac device (ICD), the ICD comprising;
at least one sensor that senses an activity level related to movement of a patient;
a memory that stores the activity level as a first coordinate of an activity data point;
a processor that generates an average activity level from a predetermined number of sensed activity levels, that stores the average activity level in the memory as a second coordinate of the activity data point, that accumulates a number of times the activity data point having the first and second coordinates occurring occurs, and that stores in the memory the accumulated number of times; and
a graphical user interface that retrieves from the memory of the ICD a plurality of activity data points, each having an associated accumulated number of times, and displays each of the plurality of activity data points with the associated accumulated number of times.

Abstract
Methods and systems are presented for displaying patient activity data from implantable cardiac device (ICD). The method includes: sensing an activity level, storing the sensed activity level as a first coordinate of an activity data point, generating an average activity level from a predetermined number of sensed activity levels, storing the average activity level as a second coordinate of the activity data point, accumulating a number of times the activity data point having the first and second coordinates occurs, and storing the accumulated number of times. These steps are repeated for a predetermined period of time, and a plurality of activity data points each having an associated accumulated number of times is stored. The method further includes graphically displaying each of the plurality of activity data points with the associated accumulated number of times.

9. A system for displaying patient activity data, comprising:
-
an implantable cardiac device (ICD) the ICD comprising; sensor means for sensing an activity level related to movement of a patient; storage means for storing the activity level as a first coordinate of an activity data point; processing means for generating an average activity level from a predetermined number of sensed activity levels, wherein the storage means stores the average activity level as a second coordinate of the activity data point; wherein the processing means further accumulates a number of times the activity data point having the first and second coordinate occurs, and wherein the storage means further stores the accumulated number of times; and display means for retrieving from the storage means a plurality of activity data points, each having an associated accumulated number of times, and displaying each of the plurality of activity data points with the associated accumulated number of times. - View Dependent Claims (10, 11)
