“…Power spectrum analysis of HRV is a non-invasive, reliable technique able to evaluate the autonomic modulation to the heart (Malliani et al 1991; Task Force of the European Society of Cardiology and the North American Society of Pacing and Electrophysiology 1996; Pagani et al, 1997). HRV has previously been used to evaluate the influence on the autonomic nervous system of different body positions and various anaesthetics, and, qualitatively, different levels of stress (Widmark et al 1998;Mohr et al 2002). Frequency fluctuations in the range of 0.04-0.15 Hz [low frequency (LF)] are, however, regarded with some controversy and are considered to be a marker of sympathetic activity, and high-frequency (HF) fluctuations in the range of 0.15-0.40 Hz are considered to be a marker of parasympathetic or vagal activity (Task Force of the European Society of Cardiology 1996).…”

“…Heart rate variability (HRV) allows an analysis of the interaction between the activities in the sympathetic and the parasympathetic nervous systems by modulation of the heart beat-tobeat interval. The HRV technique has previously been used to demonstrate the influences of different body positions, the influence of various anaesthetics on the autonomic nervous system and separate qualitative different levels of stress (Mohr et al 2002;Lucini et al 2002;Widmark et al 1998). Frequency fluctuations in the range of 0.04-0.15 Hz (low frequency, LF) are controversially considered to be markers of sympathetic nerve activity, and high frequency (HF) fluctuations in the range of 0.15-0.40 Hz are considered markers of parasympathetic or vagal nerve activity (Task Force of the European Society of Cardiology and the North American Society of Pacing and Electrophysiology 1996).…”

The object of this study was to assess the effects of magnitopuncture applied to Dazhui (DU14) point and Neiguan (PC6) points on sympathetic and parasympathetic nerve activities by power spectrum analysis of heart rate variability in healthy drivers during simulated driving. Using power spectrum analysis, the low frequency (LF) and high frequency (HF) components of heart rate variability can be calculated reflecting the sympathetic and parasympathetic activity. The 40 healthy male subjects were randomly divided into two groups: A (study group) and B (control group). All subjects were required to be well rested before the experiment. The subjects of both groups were required to perform a simulated driving task for 3 h. During the driving, magnitopunctures were applied to the DU14 and PC6 points for A while the subject performed the task for 2.5 h, and for B magnitopunctures were applied to non-acupuncture points which were 1.5 cm away from the two acupuncture points respectively over the same time. Subjective response to a questionnaire was obtained after the simulated task in the two groups. At the end of the driving task the LF component in normalized units (NU) had decreased significantly ( P<0.05) indicating a reduced sympathetic nerve activity and the HF component (NU) increased significantly ( P<0.05) indicating a increased parasympathetic nerve activity for A compared with pre-stimulation while for B no significant differences were observed. There were significant group differences in LF (NU), HF (NU) and LF:HF at the end of the driving task ( P<0.05). It was concluded that a modulating effect of magnitopuncture on sympathetic and parasympathetic nerve activities in healthy subjects was associated with the acupuncture points. The findings represent physiological evidence that magnitopuncture may reduce mental fatigue in healthy drivers.

“…In isoflurane anaesthesia, LF/HF transiently increased after induction, then decreased, while this decreased in sevoflurane anaesthesia. In previous studies, isoflurane decreased total power, LF [4], and HF [2]. In isoflurane anaesthesia, HF decreased with an increase in isoflurane concentration, whereas LF and total power showed a biphasic response downward with a second peak at 1.5 MAC of isoflurane [2].…”

Background: The purpose of this study was to compare cardiac sympathetic and parasympathetic balance using heart rate variability (HRV) during induction of anaesthesia between sevoflurane and isoflurane in combination with nitrous oxide. Methods: 40 individuals aged from 30 to 60 years, scheduled for general anaesthesia were equally divided into sevoflurane or isoflurane groups. After 100% oxygen inhalation for a few minutes, anaesthesia was induced with nitrous oxide 3 L min -1 , oxygen 3 L min -1 and sevoflurane or isoflurane. Sevoflurane or isoflurane concentration was increased by 0.5% every 2 to 3 breaths until 5% was attained for sevoflurane, or 3% for isoflurane. Vecuronium was administered to facilitate tracheal intubation. After intubation, sevoflurane was set to 2% while isoflurane was set to 1% with nitrous oxide with oxygen (1:1) for 5 min. Results: Both sevoflurane and isoflurane provoked a decrease in blood pressure, total power, the low frequency component (LF), and high frequency component (HF) of HRV. Although the heart rate increased during isoflurane anaesthesia, it decreased under sevoflurane. The power of LF and HF also decreased in both groups. LF was higher in the isoflurane group while HF was higher in the sevoflurane group. The LF/HF ratio increased transiently in the isoflurane group, but decreased in the sevoflurane group. Conclusion: Anaesthesia induction with isoflurane-nitrous oxide transiently increased cardiac sympathetic activity, while sevoflurane-nitrous oxide decreased both cardiac sympathetic and parasympathetic activities. The balance of cardiac parasympathetic/sympathetic activity was higher in sevoflurane anaesthesia.
