Patent ID: 8483843

Claim:
An implantable cardiac stimulus system comprising: an implantable medical device including a canister housing operational circuitry and at least three electrodes coupled to the operational circuitry for sensing cardiac activity while implanted; and a programmer configured to communicate with the implantable medical device after the implantable medical device is implanted in a patient; wherein the system is configured to perform the following method after the implantable medical device is implanted in a patient such that the at least three electrodes define at least first and second sensing vectors analyzable by the operational circuitry: the programmer indicates that the patient is to hold a first body position while a first analysis is performed; the implantable medical device captures data using at least the first and second sensing vectors; the implantable medical device indicates to the programmer that a first data capture for sensing vector analysis using the first and second sensing vectors is complete; the programmer, once the implantable medical device indicates completion of the first data capture for sensing vector analysis, indicates that the patient is to hold a second body position while a second analysis is performed; the implantable medical device again captures data using at least the first and second sensing vectors; the implantable medical device indicates to the programmer that a second data capture for sensing vector analysis using the first and second sensing vectors is completed; and the programmer indicates that the second analysis is complete.
