Abstract
Method and system for monitoring stress level of a subject. Beat-to-beat time variation and stroke volume variation of the heart a subject are obtained simultaneously, and a stress level indication is determined as a function of the beat-to-beat time variation and the relative stroke volume variation. More accurate and reliable estimates for stress level may be obtained.
