Research: is low heart rate variability associated with emotional dysregulation?
Read this new research publication by Cattaneo et al. (2021) that discusses polyvagal theory and the neurovisceral integration model to better understand how heart rate variability (HRV) relates to emotional dysregulation, cognitive performance and psychopathological disorders.
The authors identify several studies that support the findings of Dr. Porges and other researchers on the bidirectional relationship between the heart and mind.
The study examines the relationship between heart rate variability (HRV), emotional dysregulation, psychopathological dimensions and prefrontal dysfunctions. The study relies on Polyvagal Theory and the Neurovisceral Integration Model to understand the complex interactions between the autonomic nervous system, emotional regulation, cognitive functions and psychopathology.
Key points:
1. Heart rate variability (HRV): HRV is a measure of the variation in time between heartbeats and is considered an indicator of autonomic nervous system activity. Low HRV is associated with poorer emotional and cognitive functions and various psychopathological disorders.
2. Polyvagal theory and neurovisceral integration model: These theories provide a framework for understanding the relationship between the autonomic nervous system and behavior. They emphasize the importance of vagal activity (measured via HRV) for emotional regulation and social communication.
3. Emotional Regulation: High HRV is associated with better emotional regulation and coping strategies, while low HRV is associated with emotional dysregulation, visible in behaviors characterized by anxiety and rigid attentional processes.
4. Psychopathology: Low HRV is considered a possible explanation for several mental disorders, including anxiety disorders, panic disorder, schizophrenia, and borderline personality disorder.
5. Neuropsychological functions and prefrontal cortex: There is a relationship between HRV and prefrontal brain functions. High HRV is associated with better prefrontal performance and cognitive functions, including attention and executive functions.
6. Implications for Treatment and Research: The findings suggest that HRV may serve as a biomarker for emotional and cognitive dysfunctions and psychopathology. This has implications for both clinical practices and future research.
Questions for consideration:
1. How can interventions aimed at improving HRV contribute to better emotional regulation and reduce psychopathological symptoms?
2. In what ways can future studies further explore the relationship between HRV and specific psychopathological conditions?
3. How can knowledge about the relationship between HRV and prefrontal functions be applied in neuropsychological rehabilitation and therapy?
