“…This technique was effective in 52 of 54 control attempts made in five patients. Attarsharghi et al (2009) applied an adaptive control method with delayed feedback to prevent or control pathological undesirable arrhythmias described with the aid of the logistic map to model the interval between heartbeats. López et al (2010) used a control algorithm with proportional gain and in the ∞ L norm of tracking error signal, applied to a cardiac model proposed by Gois and Savi (2009), in order to avoid pathological behaviors.…”

The control of irregular or chaotic heartbeats is a key issue in cardiology. In this regard, chaos control techniques represent a good alternative since they suggest treatments different from those traditionally used. This paper deals with the application of the extended time-delayed feedback control method to stabilize pathological chaotic heart rhythms. Electrocardiogram (ECG) signals are employed to represent the cardiovascular behavior. A mathematical model is employed to generate ECG signals using three modified Van der Pol oscillators connected with time delay couplings. This model provides results that qualitatively capture the general behavior of the heart. Controlled ECG signals show the ability of the strategy either to control or to suppress the chaotic heart dynamics generating less-critical behaviors.
