How to change heart rhythm but not rate?

    How to change heart rhythm but not rate?

    This probably has an obvious answer...

    I am writing a scenario and I need to be able to change the heart rhythm to "ischemia" at a certain point. However, I seem to have to set the rate at the same time, as in "ischemia at a rate of 97."

    Problem is, depending on previous branches, drugs given, etc, the rate might not be at 97 when I want to invole the ischemia waveform. So I get an abrupt change in rate, say from 125 without ischemia, to 97 with ischemia.  Is there any way around this?

    I though about writing a whole series of conditional frames, like "if HR>110, then ischemia at 110;  if HR>105, then ischemia at 105; if HR>100, then ischemia at 100, etc.  Problem is I'd need to write dozens of frames to do it that way.  What am I missing here?

    Unfortunately, I don't think you are missing anything.  I believe you have found a flaw in the programming- that rate and rhythm should be independant of each other for just such a reason. Makes you have to do a bit of on the fly adjustments during the scenario. If you have multiple people using the same scenario, you may want to add a comment to the frames where these changes occur to remind them to adjust the rate back to where it was before the frame changed.

    This is definitely a bug in the software. We've been struggling with this for a couple years now. The best way to get this addressed in future versions of the software is to contact tech support and start a "complaint" about it. The more complaints they get, the better the chance of it getting looked at by the development team.

    a posibility is create an event like "change rythm" and create a handler for this one with the new rythm and same rate,
