A Survey Paper on ECG Data Compression techniques and Proposing a New Method to achieve a Low PRD Value

Data compression has its application in many fields and so as in the field of medical science. ECG is an important parameter that measures patient’s health and reports abnormalities if any. 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. This requires very less time for decompression. It also provides low noise and has excellent restoration quality.
