Heart disease is one among the most factors inflicting death in developed and developing countries. Heart rate monitoring plays an important role in detecting abnormalities in heart rhythm. This paper proposes cardiac arrhythmia detection method based on the heart rate using ballistocardiogram (BCG) signal. The BCG signals are acquired for 10 minutes from 20 subjects using piezoelectric sensors and National Instruments data acquisition card (DAQ) and processed using National Instruments LabVIEW. Heart rate is calculated from JJ intervals, that are obtained using peak detector with thresholding. Cardiac arrhythmias like tachycardia and bradycardia are detected based on the heart rate.keywords -Ballistocardiogram, Cardiac Arrhythmia.
