Abstract:
Objective To investigate the effect of old myocardial infarction on the heart rate variability.Methods Totally 86 patients with old myocardial infarction and 78 healthy people were enrolled in the study.Twenty-four-hour heart rate variability in the time domains including NN,SDNN,SDANN,RMSSD,and PNN50 and the frequency domains including VLF,LF,HF,and LF/HF were analyzed.Results Both the time domain and frequency domain indexes of the heart rate variability in patients with old myocardial infarction significantly decreased than those in the healthy peolple(P 0.05).Conclusion There might be autonomic nervous system dysfunction in the patients with old myocardial infarction.
