System and method for measuring a subject's response to an event - Patents.com

Abstract

The invention relates to a method (30) comprising acquiring (32) EEG data from a subject (16) using an EEG monitoring system (12), the data being recorded over a first time period, the first time period including an event; acquiring (34) heart rate data from the subject (16) using a heart rate monitoring system (14), the heart rate data being recorded over a second time period, the second time period also including the event; scaling (36) an EEG template to fit the event EEG data at a specified delay after the event to derive an EEG scaling factor; determining (38) a change in heart rate due to the event using the heart rate data; and combining (40) the EEG scaling factor and the change in heart rate to generate a score indicative of the subject's response to the event.
