The Civil Aviation Pilots hypertensive patients heart rate variability and baroreflex sensitivity analysis: analysis of heart rate variability and baroreflex sensitivity in civil flying personnel with hypertension
To explore the Civil Aviation Pilots hypertensive patients cardiovascular autonomic nervous regulation of the changes to provide a reasonable basis for hypertension control. Methods: To use conventional AR spectral analysis methods on 14 cases of civil aviation pilots hypertensive patients and 14 healthy pilots Short-term heart rate variability (HRV) signal analysis, sequential analysis at the same time using its baroreflex sensitivity (BRS). Results: Compared with the control group, the HRV hypertensive patients decreased significantly, the difference was significant (P <0.05), showed total power (TP), low-frequency power (LF), high-frequency power (HF) and the normalization of the high-frequency components (HFn) lower, and normalization of the low-frequency component (LFn) and LF / HF increased; ? the BRS hypertensive patients compared with the control group decreased, the difference was significant (P <0.01). Conclusions: Pilots hypertensive patients regulatory function of the cardiovascular autonomic nervous obvious anomaly, a relatively sympathetic regulatory activities increased, vagus nerve regulatory activities be curbed. flight personnel in the control of hypertension, should strengthen its regulatory function of the autonomic nervous analysis.
