Abstract:
1. A system for tracking effectiveness of pacing therapy to a patient: a therapy delivery module configured to deliver pacing therapy to a patient's heart; sensing apparatus configured to monitor electrical activity of the patient's heart, wherein the sensing apparatus comprises a plurality of electrodes; a sensing module coupled to the sensing apparatus and configured to monitor two or more electrical vectors of the patient's heart using the plurality of electrodes of the sensing apparatus during pacing therapy; and a control module coupled to the therapy delivery module and to the sensing module and configured to: initiate the delivery of pacing therapy to the patient's heart over a plurality of heartbeats, monitor two or more electrical vectors of the patient's heart during pacing therapy for each paced event of a plurality of paced events occurring over a period of time, wherein monitoring the two or more electrical vectors comprises sensing a morphologic waveform corresponding to the paced event at each electrical vector of the two or more electrical vectors using a different pair of electrodes of the plurality of electrodes, analyze whether each paced event of the plurality of paced events has a predetermined level of effectiveness based on at least one feature of the sensed morphologic waveform for each electrical vector of the two or more monitored electrical vectors, and track a pacing effectiveness ratio, the pacing effectiveness ratio being the ratio between the amount of paced events over time having a predetermined level of effectiveness and the number of paced events.
