Transition from Ventricular Tachycardia to Ventricular Fibrillation as Function of Tissue Characteristics in a Computer Model
A simplified quantitative ionic model of cardiac action potential, which reproduces accurate restitution curves, is used in conjunction with global tissue characteristics such as rotational cell anisotropy and periodic boundaries to study the transition from ventricular tachychardia (VT) to ventricular fibrillation (VF). We give an explanation for the experimental observation that there is a mi...
متن کاملComputer Simulation of Ammonia Cold Shot Converter
A mathematical model is developed and tested with plant data for the ammonia cold shot converter of Razi Petrochemical Complex. The model is based on a material and energy balance in a differential element of beds and is subjected to the assumptions of uniform distribution of temperature and composition through a general cross section and negligible mass and heat transfer in axial direction. Th...
متن کاملComparative study of computer simulation softwares
One of the methods for analyzing systems is simulation. Network simulation is a technique that models the behavior of the network by performing transaction calculations between different network entities and using mathematical formulas and taking observations from network products. A network simulator is a piece of software or hardware that predicts the behavior of a computer network without a ...
متن کاملVentricular Fibrillation
The cellular events during the initiation and maintenance of ventricular fibrillation (VF) are poorly understood. We developed a nonischemic, isolated, perfused rabbit Langendorff preparation in which sustained VF could be induced by alternating current (AC) and which allowed changes in perfusate composition. We also used Na+-K+ pump inhibition (10 ,uM ouabain or K'-free perfusate) to induce VF...
متن کاملModification of Ventricular Fibrillation
Abrupt occlusion of the left anterior descending coronary artery was performed on 43x unanesthetized farm pigs in order to evaluate the relative effects on the latency to ventricular fibrillation (\VFL) of 1 ) adaptation of the animals to the laboratory, and 2) beta-receptor blockade by propranolol. Compared to control values, VFL, was greatly lengthened (i.e., VF delayed or prevented) by adapt...
