Abstract
Efficient and reliable electrocardiogram (ECG) compression system can increase the processing speed of real time ECG transmission as well as reduce the amount of data storage in long-term ECG recording .In this paper, different methods of ECG data compression are compared. This paper has done a survey of various kinds of ECG data compression techniques. The proposed method of ECG Data Compression is intended to attain a lossless compressed data with relatively high compression ratio (CR) and low PRD (Percent Root Mean Square Difference). Different transformation may be used for data compression. This requires very less space for decompression. It also provides low noise and has excellent restoration quality. It reduces redundancy that occurs in an ECG signal.
