Identification of R-peaks to Detect Ventricular Fibrillation, Ventricular Tachycardia and Atrial Fibrillation

Many types of arrhythmias are identified by where they occur in the heart either in the Atria or Ventricles and what happens to the heart rhythm when they occur. Arrhythmias that begin in the atria are called atrial or super ventricular arrhythmias. Arrhythmias that begin in the ventricles are called ventricular arrhythmias. These ventricular arrhythmias begin in ventricles. The rhythm of heart can be measured using ECG signal. In this work, we are detecting R-peaks using Pan and Tompkins algorithm by which we are calculating the heart rate from ECG signal. These heart rate and abnormalities in ECG signal help us to detect VT (Ventricular Tachycardia), AF (Atrial Fibrillation) and VF (Ventricular Fibrillation). This Pan and Tompkins algorithm is implemented using MATLAB.
