Abstract :
The authors propose a new transformation method as an electrocardiogram (ECG) data compression. They use a biorthogonal basis in the restoring procedure to overcome shortcomings in the existing transformation methods. Using the biorthogonal basis, nonuniformly selected original amplitude can be used in the restoring procedure instead of the transformation coefficients of conventional methods. Flexibility in selection of amplitude samples will be useful to produce a reasonable ECG data compression depending on the demand of a cardiologist
