System for the creation of patient specific templates for epileptiform activity detection

摘要

An epileptiform activity patient template creation system is provided which permits the 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 to a computer software package which operates within a computer workstation having a processor, disk storage and display for storing, processing and displaying patient EEG signals. The computer processor in conjunction with the software package allows for the marking of the initiation/termination of electrographic seizures within the patient's displayed EEG signals. Epileptiform activity segments are extracted from at least one of the EEG signals with the activity segments including a marked initiation of a seizure. Subsequently, a seizure data set simultaneously displaying a number of the epileptiform activity segments is shown on the display monitor. Epileptiform activity is then detected from the displayed segments by an epileptiform activity detection algorithm having at least one programmable epileptiform activity detection parameter. The template is then created and modified to optimize epileptiform activity detection. The final template can then be downloaded to an implantable neuropacemaker for epileptic seizure control through responsive stimulation.
