ABSTRACT
This study designed one index of HRV from Poincaré plot named 5SSD1 by the present authors, which can describe the characteristics of the heart rate dynamics with 5-second data. We also investigated the feasibility of its clinical application in real-time monitoring of the activity of autonomic nervous system. We studied 20 patients scheduled for oral maxillofacial surgery. ECG recording was obtained when kept awake and anesthetic states, respectively. We calculated the correlation coefficients between the 5SSD1 and the other quantitative indicators, such as 5-minute HRV in the time domain, the frequency domain, and the Poincaré plot families. The correlation between 5SSD1 and indicators, such as rMSSD, HF and SD1 of 5-minute HRV was significantly high, with r=0.995, 0.895, 0.996, respectively, at P<0.01 for all. However, the correlation between 5SSD1 and the other indicators of 5-minute HRV was relatively poor. It was proved that 5SSD1 could be used to assess the activities of the autonomic nervous system in real-time, and the stable and reliable results might play more roles in the clinical applications.
