Why the study?
Does heart rate variability predict mortality in septic patients?
Does heart rate variability predict mortality in septic patients?
Heart rate variability, particularly SDNN, may serve as a predictor of mortality in patients with sepsis.
HRV parameters may aid sepsis mortality prediction; leaves open prospective validation before clinical adoption.
Several HRV parameters are reduced in nonsurviving septic patients in short-term recording. Two studies have found that SDNN is associated with mortality in sepsis, even after adjusting for possible confounding factors.
