1. Procedure for the detection of stress state, wherein ambulatory heart beat signal is measured, characterized in that segments are defined from heart beat signal with a chosen rule for segmentation, and at least one segment describing a physiological state with elevated cardiac activity due to physical workload and/or increased metabolic rate is identified and excluded, if exists, and segments other than the excluded segments are detected for a potential stress state, which is identified using a predetermined rule for the heart beat signal.
