After a year of trying to combine the .ogg file I made personally in Adobe After Effects with the display of the LifePak 15 heart monitor, Riouken has helped bring them together ingame.
Keep in mind that this is very alpha version and that I'm working on more heart rhythms. But, here's the link:
Each rhythm will correlate to a specific health value and will have Blood pressure and heart rate info posted on it. The heart monitor will only be available in the helo or Ambulance though. Hope you enjoy.
