Abstract :
ECG voltage records against time in seconds reveal the electrical status of the heart. Change in the waveshapes of scalar ECG records contain the diagnostic information of clinical significance. The electrophysiological ECG biosignal is weak in nature. Interference preventive methods are discussed in this paper to improve signal to noise ratio as well as linearity and reliability of the ECG records.
