Abstract:
Objective:To observe the changes of the different frequency domain of heart rate variability after the partial block of the sympathetic and vagal activity and to prove the correctness of the analysis system.Methods:Six healthy volunteers were injected intravenously with metoprolol (5mg )and six with atropine (2mg).The heart electronic signals were collected 30 minutes before the injection and 30 minutes after the injection.The collection and analysis system were provided by the electrodynamic engineering college of the Chongqing University.The values of the HF,LF,VLF and ULF were assayed and the changes between two drugs and among the different time were compared.The time domain was calculated as well.Results:SDNN,rMSSD and pNN50 were increased while HRV triangle value was decreased after the injection of metoprolol.The comparative value of the HF increased from 34.45% to 50.03%(p
