Hey guys!
after loading a patient , what can i do in order to see one of the cardiac arrhythmia types?
is there’s any action on click i can do?
there’s a way to define that the patient will have some cardiac arrhythmia in a specific point of the simulation?
the engine supports all types of cardiac arrhythmia ?
thank you very much!

Sure, you can use our Arrhythmia action
You can read about it here

after i read your ref, how can i use “Arrhythmia action” ?
i’m implementing it in unity3d, and i can’t see any class\script with this name.
what am i missing?

I have not released a new version of the Unity asset to the store in a while
I hope to do so in the next month
I do have some builds you can test out here
But they only support windows currently.
Building an asset with all the various native libraries takes a while
[Here a version that should have arrhythmia in it](https://data.kitware.com/api/v1/item/640908ef7b0dfcc98f66aea0/download)

in the meanwhile , i have created more cases for the Pulse action on click class:
case PulseAction.SinusTachycardia:
{
SEArrhythmia seaR = new SEArrhythmia();
seaR.SetRhythm(eHeartRhythm.SinusTachycardia);
driver.engine.ProcessAction(seaR);
break;
}
and applying the action on click - to get the desired Arrhythmia.
i have a questions about it:
1. when im triggering Arrhythmia, can i control on the rate? making the waves faster\slower?
2. in your next release, will you support more Arrhythmia types?
Thank you in advanced.

The Bradycardia and tachycardia heart raters are [currently hard coded](https://gitlab.kitware.com/physiology/engine/-/blob/integration/src/cpp/engine/common/system/physiology/CardiovascularModel.cpp?ref_type=heads#L2175)
We currently do not have plans to improve upon these Arrhythmia’s in the near future.
We are looking for help/support to provide a full implementation of the ACLS protocol
Any input/testing/observations on our current functionality would be greatly appreciated!

I’d love to contribute!
I will need the source in order to suggest my changes.
let’s discuss it!
