Study of Different ECG Signal Compression Techniques

Sumi Thomas, Soniya Peter

Abstract: Electrocardiogram (ECG), is the process of recording the electrical activity of the heart over a period of time using electrodes placed on a patient's body. The signal collected from the body needs to be processed and compressed before sending to monitoring center. Data compression is the process of reducing the number of bits needed to store or transmit the required data. Compression can be either lossless or lossy. Losslessly compressed data can be decompressed to exactly its original value. This paper presents a study of different compression techniques for ECG data compression.
