Abstract
Heart rate variability (HRV) is frequently perceived by clinicians as an esoteric research tool, whose results are expressed in nonintuitive units, with no clear clinical relevance. In this chapter, we show that HRV analysis is feasible in the acute care environment. Acceptance of online monitoring by clinicians may be improved by using more intuitive expression of results, including graphical expression via tachograms. HRV provides useful information on autonomic nervous system regulation of cardiac activity, as shown in various conditions such as hemorrhage, sepsis, and brain injury. Using repeated short-term (<5 min) HRV analysis, information relevant to early prediction of prognosis, patient management, evaluation of disease severity and evolution, as well as response to treatment may be obtained in the acute care environment. It remains, however, to improve the applicability of these techniques to a particular treated patient.
