 The  Phonocardiograph  records  mechanical 
 activity of  the heart  and lungs -   cardiac sounds, murmurs and respiratory sounds 
 
 EEC's  Phonocardiograph provides high-fidelity  recording  of  heart sounds, respiratory sounds and murmurs. It has a low noise and distortion- free amplifier with a built-in  speaker for audio monitoring.
Operation 
The electronic sensor is placed on the subjectís chest. The FILTER selector and GAIN control is adjusted depending on the userís requirement of pitch  and intensity. The heart sounds can be heard clearly on the speaker or binaurals, along  with audio-visual indication by  the flashing LED indicator. From the output sockets provided, the PCG unit can be connected to an Oscilloscope or ECG/Strip-chart recorder, to obtain the Phonocardiogram
