This study investigated the relationship between autonomic cardiovascular reactivity and cardiac awareness during the following conditions: baseline, emotional picture viewing, mental stress, and heartbeat tracking. Cardiac parameters were examined by using power spectrum analysis of heart rate variability and impedance cardiography. According to their performance in a heartbeat tracking task, 38 participants were classified as good (n=19) or poor (n=19) heartbeat perceivers. Neither group differed during baseline and heartbeat tracking, but good compared to poor heartbeat perceivers demonstrated greater sympathetic reactivity during mental stress and more vagal reactivity and subjective arousal during emotional picture viewing. The results suggest that cardiac awareness is related to greater responsivity of the autonomic nervous system during situations evoking autonomic reactivity.
基线、情绪图片观看、心理压力和心跳跟踪。通过心率变异性和阻抗心动图的功率谱分析来检查心脏参数。根据他们在心跳跟踪任务中的表现，将 38 名参与者分为良好（n=19）或差（n=19）的心跳感知者。在基线和心跳跟踪期间，两组没有差异，但与差的心跳感知者相比，良好的心跳感知者在心理压力期间表现出更强的交感神经反应性，在情绪图片观看期间表现出更强的迷走神经反应性和主观唤醒。结果表明，心脏意识与在引起自主反应性的情况下自主神经系统的更大反应性有关。
