Abstract

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.
