摘要
According to the problem that traditional heart detection equipment is bulky and expensive, approach to designing and implementing portable heart sound detection instrument is proposed in this paper. After the heart sound signal is filtered and amplified by hardware circuits and FPGA, the SCM receives the pre-denoised signal and calculates the heart rate, broadcasting the result in time. Experiments show that the instrument is convenient for patients to diagnose by themselves and make patients receive treatment without delay, which improves the timeliness and accuracy of cardiac auscultation.
