Patent ID: 7572232

Claim:
A system comprising: a medical device including: a processor adapted to receive at least first sensor data obtained from a first sensor and second sensor data obtained from a second sensor, wherein the first and second sensors are each adapted to produce a time-varying physiologic electrical sensor signal, and wherein at least one of the first and second sensors is implantable; and a Z-score transformation (ZST) module included in the processor to calculate a ZST for the first sensor data and a ZST for the second sensor data, and wherein the ZST module is adapted to calculate a ZST having a first resolution for a first segment of at least one of the first or second sensor data, and to calculate a ZST having a second resolution for a second segment of the same first or second sensor data, wherein at least a portion of the second segment overlaps the first segment, and wherein the second resolution is capable of being different than the first resolution; and a display, adapted to display the ZSTs in visual correspondence with each other over time, in communication with the processor.
