Abstract A ballistocardiogram (BCG) unobtrusively records the weight variation caused by the reaction force of blood ejection and blood flow in the aorta. A BCG system was developed to record BCG signals and detect the heart beats in the BCG signal. Data from 24 healthy subjects was collected to investigate the system with simultaneous electrocardiograms (ECG) as a reference. The results show no significant difference between the heartbeats detected by the ECG and BCG system (p=0.95) with the BCG system having a sensitivity of 99.56% and an accuracy of 99.77%.
