Closed-loop feedback control suppresses alternans and stabilizes 1:1 responses in paced cardiac cell models.
Theoretical modeling shows that closed-loop feedback control can suppress cardiac alternans, with the necessary gain depending on the slope of the standard restitution curve.

Model-based feedback stabilizes cardiac rhythms; hypothesis-generating and requires experimental validation before any clinical consideration.
Tolkacheva et al. (2004) studied Cardiac alternans. Closed-loop feedback control was evaluated on Stability of the 1:1 response pattern and suppression of alternans. Closed-loop feedback control in a two-dimensional mapping model of a paced cardiac cell can suppress alternans and stabilize the 1:1 response pattern based on restitution curve slopes.
