...Recently, wavelets have been applied to several problems in electrocardiology, including data compression [15]–[17], the analysis of ventricular late potentials [18], and the detection of ECG characteristic points [19], [20]....

...Most lossy ECG compression algorithms belong to either of the following categories: direct data compression methods [7]‐[9], which detect redundancies by direct analysis of actual signal samples or transform methods [ 5 ], [6], [10], which first transform the signal to some other time-frequency representation better suited for detecting and removing redundancies....
