Abstract

The invention provides an epilepsy interval electroencephalogram signal processing method and a device, a storage medium and equipment, and the method comprises the steps: obtaining a target electroencephalogram signal; filtering the epilepsy interval electroencephalogram signal to a frequency band range corresponding to an abnormal waveform, and extracting an envelope line; determining sampling points corresponding to all sampling moments, and determining a signal threshold; taking the sampling time corresponding to the sampling point not less than the signal threshold as an abnormal time point, and determining a corresponding abnormal time period and an electrode position; and taking the interepileptic electroencephalogram signals corresponding to all abnormal time periods of the interepileptic electroencephalogram signals as abnormal signals. Through the technical scheme provided by the embodiment of the invention, the extraction efficiency of abnormal electroencephalogram signals is improved, human errors can be avoided, and the accuracy can be improved; and processing is carried out based on the interval electroencephalogram signals, so that the method has relatively good universality, and the defect of poor applicability of electroencephalogram evaluation in the attack stage can be overcome.

Description

technical field [0001] The present invention relates to the technical field of EEG signal processing, in particular, to a processing method, device, storage medium and equipment for EEG signals during epileptic periods. Background technique [0002] Epilepsy is one of the most common neurological diseases, and there are about 50 million epilepsy patients worldwide. So far, epilepsy in most patients cannot be cured, and the condition can only be controlled by long-term medication. [0003] EEG is a direct measurement of brain activity, and it is currently one of the most important detection methods for clinical neurologists to diagnose epilepsy. The EEG of epilepsy is divided into two states: seizure period and interval period. The seizure period refers to the performance of epileptic seizures, usually accompanied by limb convulsions, rigidity, loss of consciousness, etc.; Electrically recorded moments without seizures. Patients usually do not experience abnormal symptomat...
