Older people's cardiac responses as indicators of stress in familiar and unfamiliar environments

Little is known about older people's physiological and emotional responses to environmental triggers. We examined this by estimating cardiac stress from heart rate variability (HRV). Thirty‐eight participants were monitored while observing environmental scenarios at familiar and unfamiliar loca...

Description
Summary:Little is known about older people's physiological and emotional responses to environmental triggers. We examined this by estimating cardiac stress from heart rate variability (HRV). Thirty‐eight participants were monitored while observing environmental scenarios at familiar and unfamiliar locations. Image scenarios included pedestrian and driving scenes in a random order. HRV indices including heart rate (HR), QT variability index (QTVI) and Total HRV Power (TP) were quantified. Familiar locations were associated with higher HR (p
