The influence on HRV cascades from the Central Autonomic Network regulating the Autonomic Nervous System to cardiac activity.

There are two theories that explain the psychophysiological aspects of HRV, the polyvagal theory and the the neurovisceral integration theory. The polyvagal theory highlights three main ordinal processes, inactive response to an environmental threat, the active response to an environmental threat, and the fluctuation between the connect and disconnect to an environmental threat. The neurovisceral integration views the Central Autonomic Network as the decision maker of cognitive, behavioral and physiological regulation as they pertain to a continuum of emotion. While both theories highlight the integration of emotion, they each represent a different viewpoint. The polyvagal Theory is responsible for emotional expression whereas, the Neurovisceral Integration model is responsible for emotional regulation.
