Signal generator in Microcap 12...

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?

Hi Jasen,
I was misunderstood. 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.

His answer was to the point nevertheless: Import your data into a
PWL source.

USR (user) source. Save your voltage levels as a series in a plain text file with the extension .usr
