ECG Analysis and R Peak Detection Using Filters and Wavelet Transform

Er. J.S Dhir Er. N.K. Panag

The objective of the paper is to develop an efficient R-peak detection. The cardiac arrhythmia shows the abnormalities of heart which is the threat to human. This paper deals with the ECG (electrocardiogram) analysis and the detection of R-peak . But to analyse an ECG signal, the first step is to remove noise from the signal. Once the signal is free from noise the Discrete wavelet transform is applied to extract the R-peak location and the amplitude in mv(millivolts). The accuracy of the determined location of R peak is essential for the other ECG performance stages.The cardiac abnormalities which are found as Tachycardia and Bradycardia can be easily identified and the algorithm is implemented in MATLAB R2012a.
