Wow, that is quite a humdinger. There are plenty programs available to 
do the reverse, in other words create an ECG graph from a recorded 
hartbeat. If you have the file in one of the (proprietary) file formats 
like .ecg or similar, then you might stand a slim chance. I do not know 
of any tool that can re-digitise graphical data.
