Stability of Cardiac Action Potential Duration under Periodic Pacing.
Action potential duration (APD) alternans is believed to be a loss of stability and contributes much to the reentry arrhythmias. The purpose of this study is to analyze the stability conditions for one-dimension model and higher dimension model. These criterions are concluded by linear stability analysis in nonlinear dynamics. They should be useful for finding of cardiac control algorithms in low energy defibrillation and the designing of antiarrhythmic drug.
