Integrated Physiological Interaction Modeling and Simulation for Aerobic Circulation with Beat-by-Beat Hemodynamics
نویسندگان
چکیده
This chapter describes a simulation system for modeling and testing aerobic circulatory physiology on the virtual environment. There have been many models of the biological system at various scales and from various viewpoints, intended to simulate physiological changes and pathological conditions (McLeod, 1966). However, these models are designed primarily for medical education, and are unsuitable as practical tools for clinical diagnosis. The reason for this unsuitability is their insufficiently accurate quantitative representation of the physiological system compared to clinical data or the results of animal experiments (Ackerman, 1991). A further problem in developing practically useful models of biological systems is the need for expert physiologists to engage in computer programming in order to create the mathematical models. The useful modeling and simulation tool for an integrated circulatory system is important for physiological diagnosis and evaluation.

Quantification of Left Ventricular Function With Premature Ventricular Complexes Reveals Variable Hemodynamics.
BACKGROUND Premature ventricular complexes (PVCs) are prevalent in the general population and are sometimes associated with reduced ventricular function. Current echocardiographic and cardiovascular magnetic resonance imaging techniques do not adequately address the effect of PVCs on left ventricular function. METHODS AND RESULTS Fifteen subjects with a history of frequent PVCs undergoing car...
متن کاملCardiac cycle length modulates cardiovascular regulation that is dependent on previous beat contraction history.
Previous studies of the beat-to-beat regulation of left ventricular performance in the intact cardiovascular system have shown that the performance of the left ventricle on any one beat is influenced by the mechanical events of the previous beat, so-called previous beat contraction history. The general hypothesis investigated in this study is that previous beat contraction history occurs becaus...

An initial experimental study was conducted to evaluate the effects of binaural beats on fish growth performance. A 90-day trial with four triplicate groups was conducted with 240 zebrafish, Danio rerio, under aquarium conditions. Binaural beat file complexes were played for each aquarium using computer controlled directional speakers for 0 min d-1(Control), 90 min d-1(Group 1), 180 min d-1 (Gr...
متن کاملAtrioventricular plane displacement is the sole mechanism of atrial and ventricular refill.
THE MECHANISM OF HEMODYNAMICS on the venous side of circulation has a fundamental uncertain issue: the mechanisms of the venous blood return into the heart and beat-to-beat atrial and ventricular refill are unclear. Commonly acknowledged factors, such as skeletal and smooth muscle contractions, thoracic suction, one-way valves in the limb veins, gravity, diastolic suction (6, 7, 11), cannot be ...
متن کاملAdaptation to mechanical load determines shape and properties of heart and circulation: the CircAdapt model.
With circulatory pathology, patient-specific simulation of hemodynamics is required to minimize invasiveness for diagnosis, treatment planning, and followup. We investigated the advantages of a smart combination of often already known hemodynamic principles. The CircAdapt model was designed to simulate beat-to-beat dynamics of the four-chamber heart with systemic and pulmonary circulation while...
