A Review of ECG signals for Human Emotion Detection

Abstract

This article evaluates the present development by means of literature review in determining the association between emotions, mainly worry, and the various physiological signals with special attention on the exclusive patterns of the electrocardiogram or ECG waveform. An initial investigation was carried out to evaluate which aspects in the ECG waveform can be most suitably related with worry, except from those. Hence, it has been observed that emotion identification utilizing particular aspects of ECG is investigated to a lesser degree compared to other physiological reactions like speech signals, skin conductance and temperature, facial expression, heart rate and blood pressure. With the initial investigation, it was further discovered that the T waves levels out consequently and there is some likelihood of P waves.
