Hi, I need to define a signal generator (voltage) of a heart beat. I have one heart beat cycle in text file format (time voltage): t1 v1 t2 v2 . . tn vn Could anybody help me to define such a generator in Microcap 12?

I'm not looking for the ECG data (voltage vs. time). I already have it. In fact from the same website. My problem is how to put this data into a schematic primitive (voltage/signal generator) that will drive the schematic that I want to simulate with Microcap 12. Stachu
