Key result
Heart rate variability provides noninvasive autonomic assessment with prognostic and therapeutic potential in critical illness.
Why the study?
The autonomic nervous system plays a central role in critical illness, and heart rate variability offers a practical, noninvasive window into its function with potential applications for prognosis and treatment.
Heart rate variability provides a practical, noninvasive method to assess autonomic function and may have prognostic and therapeutic applications in critical care.
HRV offers a noninvasive autonomic window in critical illness; leaves open its prognostic and therapeutic utility pending validation.
The autonomic nervous system plays a central role in critical illness. Heart rate variability offers clinicians a practical, noninvasive window into its function, with potential applications for prognosis and treatment across critical care populations.
