A dynamic control technique was used to suppress a cardiac arrhythmia
called an alternans rhythm in a piece of dissected rabbit heart. Our c
ontrol algorithm adapted to drifting system parameters, making it well
suited for the control of physiological rhythms. Control of cardiac a
lternans rhythms may have important clinical implications since they o
ften precede serious cardiac arrhythmias and are a harbinger of sudden
cardiac death.
