人们对老年人对环境诱因的生理和情感反应知之甚少。我们通过从心率变异性(HRV)估计心脏应激来检验这一点。38名参与者在观察熟悉和陌生地点的环境情景时进行了监测。图像场景包括随机顺序的行人和驾驶场景。对心率(HR)、QT变异性指数(QTVI)、心率变异性总功率(TP)等指标进行量化。熟悉的地点与较高的HR相关(p？
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?
