Abstract: As there are various difficulties associated with auscultation techniques, we have devised two techniques for visualising heart sound and motion to assist in the understanding of heartbeat for both doctors and patients that: 1) auscultatory sound was visualised by both FFT-image and wavelet-image in order to find abnormal heart sound; 2) a new technique for visualisation was established to show global and simultaneous heart motions. To overcome difficulties in auscultation, these techniques can be applied to the detection of heart disease and to the digital database management of the auscultation examination.
