| Outline of Final Research Achievements |
It is recently described that bio-signals are getting more simple, regular, and predictable in pathological state. We studied whether complexity analysis of integer heart rate(1440data/day) measured with Bed-side monitor could predict severity or outcome in ICU settings. In septic patients, there were significant correlations between multi-scale entropy (MSE) and APACHE II score or MSE and SOFA score. In post resuscitation patients, MSE, approximate entropy, and Detrended fluctuation analysis of integer heart rate of first 24hours after return of spontaneous circulation in good outcome patients were significantly higher those in poor outcome patients.
Thus, less variability of integer heart rate strongly indicates more serious state or poor outcome.
