Abstract: Disclosed are a clinical support system and associated method for automatic real-time detection of clinical deterioration events in a patient. Existing clinical support systems typically rely on alarm generation based on simple threshold values. This often results in too many alarms, including false alarms, which consequently results in alarm fatigue in the medical staff or in the ignoring of the alarms. The presently disclosed system and method provides an alternative to existing clinical support systems, since it incorporates clinically validated computer-implemented subroutines that provides a higher predictive value to the medical staff. The subroutines utilize thresholds and time durations, which have been clinically evaluated such that false alarms are reduced while keeping the most relevant alarms, i.e. alarms that require clinical action.

Abstract: Fluctuations in heart rate above 0.03 Hz reflect autonomic modulation of sinoatrial node activity.

Before exercise, heart rate fluctuations (spectral power) at both high (0.15-0.80 Hz) and low (0.03-0.15 Hz) frequencies were significantly higher in normal subjects than in either heart failure or transplant patients but were not different between the two groups with heart disease. During exercise, heart rate power at all frequencies rapidly and progressively decreased in normal subjects, until at peak exercise it was not different from the other two groups.
