Cardiovascular physiology, emotions, and clinical applications : are we ready for prime time?

This article is related to cardiovascular physiology mechanisms involved in emotions, in particular it shows autonomic nervous system (ANS) role. The role of ANS may be of particular importance when considering that emotional involvement may play an etiopathogenetic role many clinical conditions, such as cardiac ischemic diseases or functional syndromes. This paper describe also a modern technique, autoregressive spectral analysis of cardiovascular variabilities, employed to study in clinical setting ANS, then to study emotional involvement in many clinical conditions.
