Abstract
Stress is a major factor for the degradation of
cardiac health in first responder professionals such as firefight-ers. Monitoring stress during real events might be the key for
controlling this problem. In this paper we inspect how standard
heart rate variability (HRV) measures are associated with the
self-perception of stress of firefighters in action, supported by
an advanced technological solution to acquire this data. Results
obtained from more than 94 hours of annotated ECG recordings
of firefighters in action are promising, showing positive associ-ation with various standard HRV measures. Given the richness
of the gathered data, we have also measured the association of
the HRV measures with the stage of a firefighting event (pre,
during, post), obtaining some interesting results that hint that
the psychological impact of the post-event may be one of the
most concerning situations for a firefighter, motivating further
studies on this in the future.
