System, apparatus and method for diagnosing seizures

摘要

Systems and methods can be used to help discriminate between epileptic and non-epileptic seizures based on a relationship between the postictal heart electrical activity and the preictal heart electrical activity. Also disclosed is an approach to determine an R-R interval by using a time-invariant complex wavelet transform.

主权项

1. A non-transitory machine readable medium having instructions to perform a method comprising:
detecting a preictal heart rate associated with a given event for a patient, the preictal heart rate being a heart rate detected during a time period prior to a beginning of the given event; detecting a postictal heart rate associated with the given event, the postictal heart rate being a heart rate detected during a time period after the given event; calculating at least one heart rate index based on a comparative analysis of the postictal heart rate relative to the preictal heart rate; determining whether the given event is an epileptic seizure event or a non-epileptic event based on the heart rate index; and providing an output identifying the given event as being epileptic or non-epileptic based on the determination of the given event.
