The paper presents a denoising algorithm particularly suited to ECG signals processing. The main stage of this algorithm consists in a MAP filtering in the wavelet domain. Its effectiveness relies on the qualities of the wavelet transform and of the statistical filter used. Tests made on ECG signals, in realistic conditions, showed very promising results. The noise is almost completely removed, while...
Cardiac resynchronization therapy (CRT) has shown clinical benefit for patients with heart failure (HF). However, up to one third of these patients do not respond to CRT. The aim of this study is to determine if specific conduction abnormalities are common to patients who respond to CRT and if these can be identified and quantified on the surface ECG. A signal averaging algorithm was developed to...
The heart's mechanical activity while pumping out blood causes the vibration of physical and the object connecting with physical. The vibration is rhythmically with the heart rate and record as ballistocardiogram (BCG) on the spinal axis of the body. It is able to know humanpsilas heart rate by measuring the vibration. BCG is weak non-stationary random signal and contains a lot of noise caused by...
