This paper illustrates a DPCM based approach for real-time compression of ECG data for real time telemonitoring application. For real time implementation a `frame' is considered with one original sample followed by 64 first difference elements. The coder compresses the non-QRS regions of an ECG data stream through stages of first difference, joint sign and magnitude coding, and run length encoding. A hard thresholding at the equipotential regions have been applied to enhance the RLE efficiency… CONTINUE READING
