John - what have you tried so far? If you are using the microphone, then consider using the audio recorder.

Are you talking about an electrocardiogram (EKG or ECG) or phonocardiogram (electronic stethoscope)?
An electrocardiogram using the sound card as input would require sophisticated instrumentation. A phonocardiogram would require only a microphone.
