1. A method of detecting cardiopulmonary coupling between heart rate variability and respiration of a subject, comprising:

  • accessing a first series of physiological data representing respiration dynamics of the subject;

    accessing a second series of physiological data representing heart rate dynamics of the subject, said second series being temporally aligned with said first series; and

    detecting cardiopulmonary coupling between said first series and said second series.
