WebBackground: Heart rate variability (HRV) is becoming increasingly important in the analysis of prepartal cardiotocography (CTG). Dawes and Redmann have developed a computer algorithm which can calculate short-term variability on the basis of CTG data. WebElectronic fetal monitoring is used to record the heartbeat of the fetus and the contractions of the mother’s uterus before and during labor. FHR baseline usually ranges from 120-160 beats per minute (bpm); however, with fetal decelerations, the heart rate usually drops about 40bpm below baseline. WebVariability Fluctuations in baseline that are irregular in amplitude and frequency Absent = amplitude undetectable Minimal = amplitude 0 to 5 bpm Moderate = amplitude 6 to 25 bpm Marked = amplitude over 25 bpm Measured in a 10-minute window. The amplitude is measured peak to trough. ender 3 pro download files
