  Heart sound stethoscope is primary stage to access diseases. In this paper
design of an electronic stethoscope with the functions of wireless transmission
is discussed. This electronic stethoscope based on embedded processor. The data
can be transmitted through wireless transmission using Zigbee module. A
microphone is used to pick up the sound of the heart beat. Acoustic stethoscope
can be changed into a digital stethoscope by inserting an electric capacity
microphone into its head. The signal is processed and amplified to play with or
without earphone. Heart sounds are processed, sampled and sent wirelessly using
Zigbee module so that multiple doctors can do auscultation. PC connectivity is
provided through serial port where from audio and video can be made available
through LAN and internet for telemedicine consultation. Heart beat signals are
sensed, sent, displayed, monitored, stored, reviewed, and analysed with ease.
