If you apply an `Arrhythmia` action with `Asystole`, the HR will drop to 0

Use the [Pulse Explorer](https://gitlab.kitware.com/physiology/explorer/-/wikis/home) to start with the StandardMale state and apply this action, let it run for a bit and Serialize the Pulse state for use in your application.

Notice, this is going to drop your MAP into/below the 30s.  
You can actually perform CPR in the Explorer if you set the Chest Compression Action to something like the following: Then you will need to keep clicking the Apply button at the proper compression timing to keep the MAP in the 40s
