The degree to which romantic partners' autonomic responses are coordinated, represented by their pattern of physiological synchrony, seems to capture important aspects of the reciprocal influence and co-regulation between spouses. In this study, we analyzed couple's cardiac synchrony as measured by heart rate (HR) and heart rate variability (HRV). A sample of 27 couples (N = 54) performed a structured interaction task in the lab where they discussed positive and negative aspects of the relationship. During the interaction, their cardiac measures (HR and HRV) were recorded using the BIOPAC System. Additional assessment, prior to the lab interaction task, included self-report measures of empathy (Interpersonal Reactivity Index and Interpersonal Reactivity Index for Couples) and relationship satisfaction (Revised Dyadic Adjustment Scale). Synchrony computation was based on the windowed cross-correlation of both partner's HR and HRV time series. In order to control for random synchrony, surrogate controls were created using segment-wise shuffling. Our results confirmed the presence of cardiac synchrony during the couple's interaction when compared to surrogate testing. Specifically, we found evidence for negative (antiphase) synchrony of couple's HRV and positive (in-phase) synchrony of HR. Further, both HRV and HR synchronies were associated with several dimensions of self-report data. This study suggests that cardiac synchrony, particularly, the direction of the covariation in the partners' physiological time series, may have an important relational meaning in the context of marital interactions.
浪漫伴侣的自主反应相互协调的程度，以他们的生理同步模式为代表，似乎体现了配偶之间相互影响和共同调节的重要方面。在本研究中，我们分析了通过心率（HR）和心率变异性（HRV）测量的夫妻心脏同步性。27对夫妻（N = 54）的样本在实验室中进行了一项结构化互动任务，他们讨论了关系中的积极和消极方面。在互动过程中，使用BIOPAC系统记录他们的心脏指标（HR和HRV）。在实验室互动任务之前的额外评估包括共情的自我报告测量（人际反应指数和夫妻人际反应指数）和关系满意度（修订的二元调适量表）。同步性计算基于双方HR和HRV时间序列的加窗互相关。为了控制随机同步性，使用逐段重排创建了替代对照。与替代测试相比，我们的结果证实了夫妻互动期间心脏同步性的存在。具体而言，我们发现了夫妻HRV的负（反相）同步性和HR的正（同相）同步性的证据。此外，HRV和HR同步性均与自我报告数据的几个维度相关。这项研究表明，心脏同步性，特别是伴侣生理时间序列中协变的方向，在婚姻互动的背景下可能具有重要的关系意义。
