摘要：ECG, electrocardiogram plays a vital role in the diagnosis of heart related problems. Good quality ECG is used by the doctors for identification of physiological and pathological phenomena. ECG is very sensitive in nature and even if small amount of noise interferes with it, the characteristics of the signal change. The main objective of the processing of ECG signal is to provide us the accurate, fast and reliable information of clinically important parameters like duration of QRS complex, the R-R interval, occurrence, amplitude and duration of P,R and T waves. This demands that the pre processed waveform should be free from noises, which in turn depends on the method of recording the ECG from the patient's body. In this pap er two important methods of ECG data acquisition are enlisted, the 3-lead and the 12 -lead ECG data acquisition systems.
