US 7,177,674 B2 · Patient-specific parameter selection for neurological event detection

Abstract

An epileptiform activity patient-specific template creation system permits a user to efficiently develop an optimized set of patient-specific parameters for epileptiform activity detection algorithms. The epileptiform activity patient template creation system is primarily directed for use with an implantable neurostimulator system having EEG storage capability, in conjunction with a computer software program operating within a computer workstation having a processor, disk storage and input/output facilities for storing, processing and displaying patient EEG signals. The implantable neurostimulator is operative to store records of EEG data when neurological events are detected, when it receives external commands to record, or at preset or arbitrary times. The computer workstation operates on stored and uploaded records of EEG data to derive the patient-specific templates via a single local minimum variant of a multidimensional greedy line search process and a feature overlay process.

Dependent claims

A method for creating a patient-specific template from at least one record of electrographic signal data stored by an implantable device, the method comprising the steps of:

uploading the at least one record of electrographic signal data from the implantable device to an external apparatus;
processing the at least one record to generate at least one parameter;
and
forming the patient-specific template from at the at least one parameter by performing a single local minimum variant of a greedy line search.

A method for creating a patient-specific template from at least one record of electrographic signal data stored by an implantable device, the method comprising the steps of:

uploading the at least one record of electrographic signal data from the implantable device to an external apparatus;
determining whether the at least one record is a statistical outlier, and if so, discarding the at least one record;
processing the at least one record to generate at least one parameter;
and
forming the patient-specific template from the at least one parameter.
