Table 1 List of timers used in the AF-VP model
From: Open source model for generating RR intervals in atrial fibrillation and beyond
Timer | Start condition | Stop condition |
|---|---|---|
AF interval timer | Arrival of AF impulse | End of AF interval |
RR interval timer | Any VS or VP event | Next VS or VP event |
AVJ refractory timer | AVJ activation | End of AVJ refractory period |
VP clock timer | Any VS or VP event | End of VP interval |
Antegrade AVJ timer | Antegrade AVJ activation | End of antegrade AVD |
Retrograde AVJ timer | Retrograde AVJ activation | End of retrograde AVD |
Antegrade ventricle timer | End of antegrade AVD | VS event or ventricle fusion |
Retrograde ventricle timer | Delivery of VP | Retrograde invasion of AVJ or ventricle fusion |
