Biological rhythms are fundamental for the understanding of the physiological functioning of
organisms, being useful in disease prevention and treatments. This work deals with the …

This paper deals with the uncertainty analysis of the cardiac system described by a
mathematical model. The model is composed of three-coupled nonlinear oscillators with …

This work deals with an investigation of randomness effects on heart rhythm analysis. A
mathematical model composed by three-coupled nonlinear oscillators coupled by time …

The rotary blood pump is one of the latest generations of left ventricular assist devices
(LVAD), helping patients to deal with shortage of cardiac output. The main challenge of the …

Background In object-oriented or acausal modelling, components of the model can be
connected topologically, following the inherent structure of the physical system, and system …

Objective. Significant aortic regurgitation is a common complication following left ventricular
assist device (LVAD) intervention, and existing studies have not attempted to monitor …

Natural phenomena have essential nonlinear characteristics responsible for the variety and
richness of behaviors. Rhythms constitute one of the most relevant manifestations of natural …

This article presents a hybrid representation of the cardiovascular system in conjunction with
a ventricular assist device (VAD). The representation is a set of switched q-LPV systems …

The deterministic model of the cardiovascular left ventricular assist device system and all of
the associated equations, figures, and tables were initially published in references [13] and …
