This paper developed a new method using wavelet package transform approximation signal to remove the baseline wander in electrocardiogram.The main idea of this method is using one or more approximation signal of Multi-resolution Analysis approaching the baseline wander characterizes of ECG signal almost fully,then remove the baseline wander,Real data results show that it has a good result based on having little harm to the other elements of signals.
