Implication
Model identifies distinct ionic triggers for DADs and EADs; hypothesis-generating for arrhythmia mechanisms, with clinical translation remaining open.

Intervention
Simulated conditions of Ca2+ overload and high-frequency pacing
O
Outcome
Mechanisms of delayed afterdepolarizations (DADs), early afterdepolarizations (EADs), triggered activity, and postextrasystolic potentiationsurrogate
This computational model elucidates the ionic mechanisms underlying early and delayed afterdepolarizations, which are key cellular triggers for cardiac arrhythmias.
