...Most lossy ECG compression algorithms belong to either of the following categories: direct data compression methods [8], [12], [25], which detect redundancies by direct analysis of actual signal samples; or transform methods [1], [3], [21], which rst transform the signal to some other time{frequency representation better suited for detecting and removing redundancies....

...The ECG signals were taken from the MIT-BIH Arrhythmia database [30] and the compression algorithms were chosen to be: analysis by synthesis ECG compressor (ASEC) with WDD minimization and with PRD minimization [20], [31], LTP [13], SAPA2 [8], and AZTEC [3]....

...Four compression algorithms were implemented (AZTEC, SAPA2, LTP, ASEC) in order to evaluate the WDD....

...These compressors were chosen, because AZTEC and SAPA2 are often referred for comparison in the literature, and ASEC and LTP are two of the best ECG compressors available today....
