Abstract: Precision medicine approaches to critically ill patients requires real-time feedback from physiological signals that are ideally easy to collect. Heart rate variability (HRV), the change in inter-beat-intervals, shows promise as a non-invasive biomarker, reflecting autonomic nervous system functioning. Our analysis of three different cohorts of critically ill patients suggests that HRV may be useful in guiding vasopressor treatment, commonly used in ICU settings for cardiovascular support.

Learning Objective 1: To investigate the relationship of changes in heart rate variability with vasopressor intervention in critically ill patients.

Learning Objective 2 (Optional): To investigate the use of HRV as a non-invasive biomarker for use in guiding vasopressor treatment in the ICU.
