Abstract

The ballistocardiogram (BCG) is an innovative noninvasive cardiac activity monitoring method. A Ballistocardiogram-Electrocardiography (BCG-ECG) measurement system was used here to collect BCG and ECG signals of 48 healthy subjects (male: 38; female: 10) with no history of cardiovascular diseases and 77 subjects (male: 33; female: 44) with coronary heart disease (CHD). Preoperative and postoperative BCG signals were also measured for some subjects. The temporal features, including the time intervals, amplitudes and energy were extracted from these subjects with the differences of these features examined using the independent Student's t-test. The results showed that the tIJ, tJK, IntHK and IntBCG features had significant differences between healthy subjects and subjects with CHD. Some features including the RR interval, tHI, tIJ, HI, IJ and IntBCG showed significant differences between preoperative BCG and postoperative BCG signals of a subject with CHD while the amplitudes of BCG decreasing during premature ventricular contraction (PVC).
