Methodology for automated signal morphology analysis in implantable electrotherapy and diagnostic systems
First Claim
1. A method of monitoring electrical activity in a patient, the method comprising:
- monitoring electrical signals within the patient using an implanted device;
identifying sense and pace event markers corresponding to sensed and paced events identified by the implanted device;
categorizing into groups time periods of the electrical signals representing a type of event marker; and
comparing the time periods of the electrical signals within at least one of the groups to identify changes over time.

Abstract
Systems and related methods for analyzing data sensed from a device implanted in a patient, such as a cardiac pacing system. The system detects and evaluates electric signals within the patient that share a common event marker. By using algorithms and graphical presentation of the collected signals having common event markers, deviations in signals over time can be identified and evaluated in consideration of taking further action related to the patient and the implanted device. The system can also be used in conjunction with an advanced patient management system that includes a programmer or repeater capable of gathering information from the implanted device and transmitting the data to a host via a communications network for evaluation at a remote location.
