Characterrization and Categorization of ECG

Electrocardiogram is the graphical record obtained by the electrocardiograph, depicting the electrical impulse of the heart as they vary during the cardiac cycle. This work is a fair attempt to characterize and categorize the ECG signals. The ECG signals are viewed in mathematical perspective and hence conclusions and equations are derived. The paper consists of schematic characterization and categorization of ECG. The characterization is done on the basis of Fourier analysis and the categorization is done on the basis of variation of ECG from the normal one.
