Nonlinear Analytical Approaches for Prediction of Alternans Mediated Cardiac Arrhythmias

Cardiac alternans, or changes in action potential duration (APD), are thought to be a precursor to lethal tachyarrhythmias like ventricular tachycardia or ventricular fibrillation, which can lead to sudden cardiac death. Linear methods for detecting alternans onset and suppression have had limited success, owing primarily to the presence of cardiac memory, in which APD prediction…
