An electrocardiogram (ECG/EKG) is an electrical
recording of the heart and is used in the investigation of heart disease. This electrical activity of the heart translates into line tracings on paper. The spikes and dips in the line tracings are called series of waves. This series of waves consists of six different waveforms, are discernible, and are differentiated as
P, Q, R, S, T and U. The most of earlier method of ECG signal
analysis for detecting PQRST was based on DSP technique for
example (Wavelet Transform and Fast Fourier Transform)
and Artificial Neural networks. While this work proposes a
simple and dependable method to detect the P, Q, R, S and T
values of an electrocardiogram (ECG) signal. This method is
based on finding a mathematical relationship between the
highest values (peaks and valleys) of the ECG waveform and
time. In this proposed method is exemplified by designing a
graphical user Interface (GUI) by using MATLAB for
detecting PQRST by using simple mathematical algorithm to
get PQRST values and draw these values on ECG wave at the
same time. This program will be devoted to the purposes of
scientific research instead of clinical diagnosis.
