Body surface potential mapping (BSPM) can give an insight of heart status in cardiovascular disease diagnosis. However, most special BSPM recording devices are cost and relatively rare. An alternative method is proposed for BSPM recording using two common 64 leads electroencephalogram (EEG) amplifiers. The recording technics includes 117 torso and three limb electrodes of silver-silver chloride, and...
As a new signal processing tool, a Modified frequency slice wavelet transform (MFSWT) is proposed for physiological signal time-frequency analysis in this study. The transform generates time-frequency representation from the frequency domain, and the reconstruction is independent of frequency slice function (FSF). To realize accurate time-frequency location of signal components, a bound signal-adaptive...
Wireless body sensor networks enabled electrocardiogram (ECG) biosensors are a novel solution for patient-centric telecardiology. With this solution, the prevention and early diagnosis of cardiovascular diseases can be effectively improved. However, the energy efficiency of the present wireless ECG biosensors still needs to be improved. In this paper, a dynamic compression scheme is proposed to deal...
