VI illnesses can be interpreted and understood, but also peculiarities in healthy individuals, as the contribution of the heart, blood vessels, and autonomic nervous system to circulatory function is expressed in an individual manner. I hope this will become clear from this presentation. I have abandoned the initial plan to also discuss the therapeutic implications that arise directly from the failure of the regulatory examination. Such a presentation, if it were to have any value, could not merely suffice with a brief reference to some treatment methods or medications, but would have to be detailed. However, that would ultimately exceed the purpose of the book: to fundamentally demonstrate the effectiveness of a differential diagnostic method and to serve as a guide for its practical use.
