Abstract: In this work we use computer simulations to test a method for controlling heart rhythm behavior based on the electrocardiogram (ECG) signal tracking. The proposed control algorithm is based on two parameters, the controller proportional gain and the norm of tracking error signal. The objective is to take out the heart rhythm dynamics from a non desirable situation to a normal specified behavior, which is given by a signal generated by a reference system. Computer simulations are carried out using as process to control a mathematical model (MS1) composed with six differential delayed equations (DDE), which, depending on model parameters, provides different dynamical behaviors, from normal behavior to non desirable performances interpreted as cardio-pathologies. In order to generate an specified normal ECG reference signal, it is used MS1 with normal behavior parameters, and as alternative model, it is used a third order nonlinear dynamical system (MS2), which pr!
oduces specific statistics such as the mean and standard deviation of the heart rate and frequency-domain characteristics of heart rate variability (HRV). By means of the proposed control law application, the heart rhythm is conduced to a neighborhood of the specified behavior and satisfactory results are obtained in numerical simulations with both reference models.
