1 Introduction
Changes of pulse rate and rhythm have attracted the attention of physicians since the earliest stages of medicine. Only recently, with the advance of computer techniques that allow for parsing heart rate variability (HRV) into components, which potentially yield information about the autonomic nervous control of cardiac activity, has there been an increased clinical interest. The technical advances, however, have not resulted in bedside application of HRV methods and evidence of their usefulness in real-world clinical practice is still limited. Moreover, from the point of view of the physician, complex approaches to HRV phenomena and the use of complicated mathematical formulae may have a rather limited implementation in everyday practice. In this chapter, several aspects of HRV are thoroughly reviewed giving priority to their physiological and pathophysiological meanings in order to render HRV more clinically useful. For that reason, technical descriptions are limited...
