Abstract
The wireless electrocardiographic monitoring system(WDMS) is designed to be long term
monitoring for the early detection of cardiac disorders. The current version of the WDMS can identify
two types of cardiac rhythms in real-time, such as atrial fibrillation(AF) and normal sinus
rhythm(NSR), which are very important to track cardiac-rhythm disorders. In this study, we proposed
the analysis method to discriminate the characteristics statistically evaluated in both time and frequency
domains between AF and NSR using various parameters in the heart rate variability(HRV). And we
applied various ECG detection methods (e.g., difference operation method) and compared the results
with those of the discrete wavelet transform(DWT) method. From the statistically results, we found
that the parameters such as STD RR, STD HR, RMSSD, NN50, pNN50, RR Trian, and TNN(p<0.05)
are significantly different between the AF and NSR patients in time domain. On the other hand, the
frequency domain analysis results showed a significant difference in VLF power(ms2), LF power(ms2),
HF power(ms2), VLF(%), LF(%), and HF(%). In particular, the parameters such as STD RR, RMSSD,
NN50, pNN50, VLF power, LF power and HF power were considered as the most useful parameters
in both AF and NSR patient groups. Our proposed method can be efficiently applied to early detection
of abnormal conditions and prevent the such abnormals from becoming serious.
