摘要：
A preliminary investigation of a wavelet packet based algorithm for the compression of single lead ECG is presented, The algorithm combines the efficiency and flexibility of wavelet packet expansions,vith the methodology of the Karhunen-Loeve transform (KLT), For selected records from the MIT-BIH arrhythmia database, an average data rate of 184.7 bits per second, corresponding to a compression ratio of 21.4: 1, is achieved, When compared with the KLT applied to the same data, the wavelet packet algorithm generates significantly lower data rates with less than one-third the computational effort.
