Heart rate variability (HRV) has been recognized as a measurement of activity of autonomous nervous system, and possibilities as an indicator of sepsis occurrence have also been investigated. One of challenges to calculate HRV is how abnormal heartbeats are eliminated because a method based on the principle of frequency modulation and demodulation over-estimates the value of HRV if there exists an abnormal heartbeat. We, thus, suggest to exclude those in advance applying $3\sigma$ rule repeatedly. Analyzing HRV of ICU inpatients with sepsis occurrences, a characteristic shape in a temporal change of HRV is observed. We also show that, in order to reveal such pattern of HRV, the ratio of the abnormal heartbeats must be less than 40\% within estimation intervals. |
