摘要：The Phonocardiography is a graphical method of
recording of the tones and noise generated by the heart with the
help of the phonocardiogram machine. Cardiovascular disease
(CVD) and heart failure (HF) are considered life-threatening and
mostly cause death. The phonocardiograph signal (PCG)
considers an indicator of abnormalities in the cardiovascular
system. It provides the ability to carry out qualitative
information and quantitative analysis of different tones and heart
murmurs. PCG plays a major role in treatment, diagnosis and
decision making of the clinical examination and biomedical
research fields. The use of simple stethoscope for diagnosis the
heart problem requires an experienced physician or doctors.
Many people with CVD and HF are dying every day because of
the lack of facilities that analysis the heart defects. Most of the
low come countries suffer from a severe shortage in the
Electrocardiogram (ECG) and PCG devices and trained
physicians and doctors. The Poor healthcare system in these
countries needs to be improved especially the problem of heart
disease diagnostics. The PCG is a technique for recording and
monitoring the cardiac acoustics by using a transducer and
microphone. This paper attempts to design a cheap and simple
biotechnical system for recording and monitoring PCG signal.
The hardware was designed and implemented using the
stethoscope, electret microphone, amplifiers, DC source, and jack
for transmitting the PCG signal to the computer. The software
was codded for monitoring and processing the PCG signal.
