Abstract :
Electrocardiogram (ECG) is one the important biomedical signal. One heartbeat of ECG consists of different segments such as QRS complex, ST segment and PR segment. Features of an ECG signal are nothing but these segments and intervals between fiducial points such as RR interval, amplitude of P, R and T wave. Several techniques are discovered and are still developing for analyzing ECG signal. Some of them are Continuous Wavelet Transform, Discrete Wavelet Transform and Pan Tompkin´s Algorithm. In this paper, with the help of extracted dynamic feature 3 different types of arrhythmia have been detected using discrete wavelet transform and thresholding method. This system is validated on standard MIT-BIH arrhythmia database and it yields about 85% of sensitivity.
