Abstract:
A system, including an implantable cardiac stimulation device, for analyzing efficacy of cardiac stimulation therapy by storing and displaying historical data related to episodes of cardiac stimulation therapy, the system comprising:sensing means for sensing a patient's cardiac rhythm which changes as a function of time;detection means for detecting a plurality of pathological cardiac rhythms;means for classifying each episode of a cardiac rhythm into one of a plurality of rate zones;stimulation means for delivering cardiac stimulation therapy to a patient's heart based on the rate zone of the cardiac rhythm;means for storing data related to each episode of cardiac stimulation therapy as a function of time, the data including information indicative of the cardiac stimulation therapy delivered, the rate zone in which the cardiac rhythm was classified and the time that the cardiac stimulation therapy was delivered; anddisplay means, telemetrically coupled to the storing means, for graphically displaying the data along an x-axis and a y-axis as a function of the time that the cardiac stimulation therapy was delivered;whereby the plurality of rate zones are displayed along the y axis and the time that each episode of cardiac stimulation therapy was delivered is displayed along the x axis.
