Cardiac and Brain Activity Correlation Analysis Using Electrocardiogram and Electroencephalogram Signals

Abstract

This study examines the correlation between cardiac function and brain activity during events of physical and psychological stress. Electrocardiography (ECG) and electroencephalography (EEG) are known procedures for investigating the correlation between the signal complexity of the brain and cardiac activity. The degree of association between ECG and EEG signals is examined and tested with various activities by simultaneously recording ECG and EEG measurements. Eight subjects participated in the conduct of the experiment consisting of 4 females and 4 males. Each were given tasks such as sit still, jog and watch thrilling video clips, while wearing ECG and EEG sensors. The results showed an increase in both heart rate and brain activity (alpha, beta, delta, and theta waves) upon stimulus activation. The study suggests that some brain activity is associated with a certain stimulus activated by different kind of tasks.
