PRE-QUALIFICATION OF AN ALTERNATE SENSING CONFIGURATION
First Claim
1. A method comprising:
- receiving a plurality of sensed signals, each of the sensed signals sensed by a respective one of a plurality of sensing configurations during a qualification event,analyzing each of the sensed signals to detect cardiac events during the qualification event; and
generating qualification information for each of the sensing configurations based on the analysis, the qualification information for each of the sensing configurations indicating whether the sensing configuration is qualified for subsequent cardiac event detection based on an accuracy of the cardiac event detection for the sensing configuration during the qualification event.

Abstract
Multiple sensing configurations may be qualified based on one induced tachyarrhythmia, e.g., ventricular fibrillation, or other qualification event during an implantation procedure. Each sensing configuration comprises a different combination of two or more electrodes used for sensing electrical signals of the heart of the patient. In some examples, an implantable medical device or other device generates qualification information for each sensing configuration, which may indicate whether the sensing configuration is qualified for subsequent cardiac event detection based on an accuracy of the cardiac event detection for the sensing configuration during the qualification event. One of the qualified configurations may initially be selected as a primary sensing configuration for subsequent cardiac event detection. Switching to an alternate sensing configuration, e.g., upon identification of any sensing integrity condition of the primary sensing configuration, may be expedited by the previous collection of qualification data for at least one other sensing configuration.
