Abstract: This paper aims at studying the various techniques and algorithms available in literature for the cancellation of various types of artifacts occurring out of the noise present in the Electrocardiogram (ECG) signal. It further aims at the enhancement of the ECG signal for proper monitoring and diagnosis of the patient. In the process of the transfer of the signal information from the location of the patient to a remote location, certain kind of noise is introduced in the signal that results in the disturbance as well as interference of the signal. Hence, the information cannot be predicted accurately. Thus, it is important to remove the resulting noise and the artifacts in order to enhance the ECG signal for proper treatment of the patient.

Keywords: artifacts, Electrocardiogram (ECG), enhancement, remote location, interference.
