【Objective】To develop a computer-assisted detecting and processing system for cardiac-vascular signals .【Method】The hardw are design uses a P-Ⅱ/233 mult imedia microcomputer system

multi-channel A/D converter

ECG electrodes

heart sound t ransducer

pulse transducer

and amplifiers and f ilters consisted with operation amplifiers .The sof tw are uses st ructure and functional modular in the visual programming environment

based on multimedia technology and w avelet transform theo ry .Visual programming lang uage Visual C + +6.0 and multimedia design tool.Authorware are also used on the 32-bit Window s platform .【Resul ts】The sy stem can detect and process ECG

heart sound and pulse signals .It can display

print or replay the results in the format of chart

w ord and sound .It also has functions of patient reco rd management

heart sound auscultation and multimedia computer-assisted instruction .【Conclusions】It is a new multi-functional cardiac-vascular signal detecting and processing system .
