Editing ECG wav files

I am working with the output from a Meditron digital stethoscope. This produces a wav file which has two tracks - one is the sound track of the heart beats and the other is the ECG waveform. In the propietary software we have with the stethoscope it is not possible to capture these two traces as a video which shows the ECG trace animation whilst playing the heart sounds. Does anybody have any ideas how this could be done with Audacity - tall order I appreciate!
