Accurate measurement of ECG template parameters

is an important requirement of quantitative ECG analysis,

particularly if the results of ECG signal analysis are to be used

for clinical purposes. However, the accuracy with which these

parameters can be measured depends mainly on the accuracy of

the analysis algorithm. This paper presents a new method for the

accurate estimation of ECG Parameters, contaminated by

instrumentation and biological noise, this method is based on

three processes. First step is removing baseline drift (lowfrequency

components) using DWT transformation techniques.
