Abstract :
Cardiac murmurs are the sounds produced by the abnormal passage of the blood flow inside the heart due to the diseased valves or tissues. Identifying the type of the murmur can diagnose the cardiac pathology related to that particular murmur. This paper describes a researched digital stethoscope that can be used as a stethoscope as well as a murmur identification device. To capture the heart beat, a chest piece of a traditional stethoscope is used with a condenser microphone attachment. Then the signal is amplified and filters out the noise and sent to the ARM processor. At the processing module, sampling is carried out and stores the sampled data if the data transmission is not being done. Then the sampled data is transmitted to a central location using radio frequency transmitter module to carry out the signal processing. If the user wishes, the signal processing can be done in the stethoscope itself since the ARM processor is in the stethoscope unit.
