The application of Poincaré plot analysis to characterize inter-beat interval dynamics has been successfully proposed in the scientific literature for the assessment of humans' physiological states and related aberrations. In this study, we proposed novel descriptors to trace the evolution of Poincaré plot shape over the lags. Their reliability in ultra-short cardiovascular series analysis was validated on synthetic inter-beat series generated through a physiologically plausible integral pulse frequency modulation model. Furthermore, we used the proposed approach for the investigation of the direct relationship between autonomic nervous system (ANS) dynamics and hedonic olfactory elicitation, in a group of 30 healthy subjects. Participants with a similar olfactory threshold were selected, and were asked to score 5-s stimuli in terms of arousal and valence levels according to the Russell's circumflex model of affect. Their ANS response was investigated in 35-s windows after the elicitation. Experimental results showed a gender-specific, high discriminant power of the proposed approach, discerning between pleasant and unpleasant odorants with an accuracy of 83.33% and 73.33% for men and for women, respectively. Graphical Abstract Olfaction plays a crucial role in our life and is strictly related to the Autonomic Nervous System (ANS) activity, which can be monitored studying Heart Rate Variability. We used the Lagged Poincare Plot approach to recognize gender-specific ANS response in 35-second windows after the elicitation through pleasant/unpleasant odorants.

量化超短心率变异性系列的滞后Poincaré图几何:自动识别气味享乐主义。

在科学文献中已经成功地提出了将庞加莱图分析用于刻画心跳间隔动力学特性的应用,以评估人类的生理状态和相关像差。在这项研究中,我们提出了新颖的描述符来追踪滞后Poincaré曲线形状的演变。通过在生理上合理的积分脉冲频率调制模型生成的合成心跳序列,验证了它们在超短心血管系列分析中的可靠性。此外,我们在30名健康受试者中使用拟议的方法研究了自主神经系统(ANS)动态与享乐嗅觉诱发之间的直接关系。选择了嗅觉阈值相似的参与者,根据Russell的回旋情绪模型,要求他们在唤醒和效价水平上对5-s刺激评分。诱导后,他们在35秒内调查了他们的ANS反应。实验结果表明,该方法具有针对性别的高判别力,可区分令人愉悦和难闻的气味,男性和女性的准确度分别为83.33%和73.33%。图形化嗅觉在我们的生活中起着至关重要的作用,并且与自主神经系统(ANS)活动密切相关,可以通过研究心率变异性对其进行监测。在通过令人愉快/令人不愉快的加香剂引发后,我们使用了“滞后Poincare图”方法在35秒的窗口中识别出针对性别的ANS反应。情感的抑扬音模型。诱导后,他们在35秒内调查了他们的ANS反应。实验结果表明,该方法具有针对性别的高判别力,可区分令人愉悦和难闻的气味,男性和女性的准确度分别为83.33%和73.33%。图形化嗅觉在我们的生活中起着至关重要的作用,并且与自主神经系统(ANS)活动密切相关,可以通过研究心率变异性来对其进行监测。在通过令人愉快/令人不愉快的加香剂引发后,我们使用了“滞后Poincare图”方法在35秒的窗口中识别出针对性别的ANS反应。情感的抑扬音模型。诱导后,他们在35秒内调查了他们的ANS反应。实验结果表明,该方法具有针对性别的高判别力,可区分令人愉悦和难闻的气味,男性和女性的准确度分别为83.33%和73.33%。图形化嗅觉在我们的生活中起着至关重要的作用,并且与自主神经系统(ANS)活动密切相关,可以通过研究心率变异性来对其进行监测。在通过令人愉快/令人不愉快的加香剂引发后,我们使用了“滞后Poincare图”方法在35秒的窗口中识别出针对性别的ANS反应。区分令人愉快和不愉快的气味,男性和女性的准确度分别为83.33%和73.33%。图形化嗅觉在我们的生活中起着至关重要的作用,并且与自主神经系统(ANS)活动密切相关,可以通过研究心率变异性对其进行监测。在通过令人愉悦/令人不快的加香剂引发后,我们使用了“滞后Poincare图解法”来识别在35秒内特定于性别的ANS反应。区分令人愉快和不愉快的气味,男性和女性的准确度分别为83.33%和73.33%。图形化嗅觉在我们的生活中起着至关重要的作用,并且与自主神经系统(ANS)活动密切相关,可以通过研究心率变异性对其进行监测。在通过令人愉快/令人不愉快的加香剂引发后,我们使用了“滞后Poincare图”方法在35秒的窗口中识别出针对性别的ANS反应。
