摘要
We demonstrate that alternans, potentially dangerous alternations in action potential morphology, can be controlled in individual cardiac cells using stimuli that modify the underlying ion channel dynamics. The best time to apply the control current is during the early plateau phase of the action potential. Elimination of alternans has important clinical implications, since alternans is linked to dangerous cardiac rhythm disorders.
