Abstract
The complex functioning of the heart continues to be of great interest in current research that deepens its knowledge. In this work, the alteration of the parameters of a system with coupling of two filtered Van der Pol oscillators was performed, with half-wave rectification and a low-pass filter, similar to that of the Wien Bridge oscillator. The behavior and system responses stability are analyzed through bifurcation diagrams, through the variation of parameters within the range of values of interest. The objective here is being to represent the electrocardiogram variations of lowest magnitude of the P and T waves, through models generated by the oscillator.
