Abstract—This paper mainly studied 24h HRV of several CHD different physiological information. LF/HF of HRV was
patients who had myocardial infarction (MI) in different part of widely used to evaluate the regulation function of
heart. The whole 24h HRV was divided to 6 sections, and LF/HF
was calculated. Primary results indicated the tendency LF/HF autonomic nervous system.
was different between anterior myocardial infarction (AMI) and After getting rid of the noise above in frequency
inferior myocardial infarction (IMI). domain by filtering, wavelet transform was applied to
pose HRV to four different frequency domains
Keywords-HRV;LF/HF;myocardial infarction;CHD including ULF, VLF, LF and HF. Here Daubechies 5
wavelet was adopted. HRV was posed to 5 levels and
NTRODUCTION
I. I then reconstructed in four different frequency domains.
During the past three decades, heart rate variability 24h HRV was divided into five sections in time scale,
(HRV) was verified to contain abundant information of that is: 00:00-05:00; 05:00-10:00; 10:00-15:00; 15:00-
