The ancient Egyptians believed that the heart was the source of human wisdom so did the traditional Indian  (TIM) and Chinese medicine (TCM) as well as Ayurveda and Tibetan medicine considering the heart as  the centre of energy and the master of body mind alignment. Hippocrates also indicated the heart as the seat of intelligence, motion, and sensation.

HRV (heart rate variability) is a measure of neurocardiac function that reflects heart– brain interactions and autonomic nervous system (ANS) dynamics . An optimal level of HRV  reflects healthy psychophysiological function and self-regulatory capacity, adaptability, or resilience.  Positive emotions  have been found to broaden the scope of perception, cognition, and behaviour by enhancing faculties such as creativity  and intuition .

The heart’s rhythmic beating patterns not only reflect the individual’s emotional state, but play a direct role in determining emotional experience. At the physiological level, afferent input from the heart is conveyed to the subcortical regions of the brain that are involved  in perceptual, cognitive, and emotional processing, and affect diverse aspects of  behavior and consciousness experience .

The heart plays a unique role in synchronizing the activity of multiple systems of the body across different levels of organization in orchestrating the flow of information throughout the psychophysiological network. As  the  most powerful generator of rhythmic electromagnetic field and information patterns in the body,  the heart is in continuous connection with the brain and other bodily organs and systems through multiple pathways: neurologically (through the transmission of neural impulses), biochemically (through hormones and neurotransmitters), biophysically (through pressure and sound waves), and energetically (through electromagnetic field interactions).  

The heart and the brain, together  in a system-wide process, are involved in receiving, processing, and decoding intuitive perception but the heart receives intuitive information before the brain and may have  stronger  influence.
