Applying nonlinear dynamics to cardiac arrhythmias reveals that discordant alternans can arise spontaneously from symmetry-breaking dynamical instabilities, suggesting new strategies for prevention.
Understanding the nonlinear dynamics of cardiac alternans bridges subcellular calcium signaling and tissue-level arrhythmias, offering novel theoretical frameworks for predicting and preventing sudden cardiac death.
May inform arrhythmia prevention strategies; extends nonlinear models but leaves clinical translation open.
Applying the techniques of nonlinear dynamics to cardiac arrhythmias sheds light on their genesis and suggests new strategies for preventing them.
