Bueno-Orovio-Cherry-Fenton Model

The Bueno-Orovio-Cherry-Fenton model (BOCF model) is a mathematical model used in the field of cardiac electrophysiology to simulate the electrical activity of the heart, particularly focusing on the dynamics of cardiac arrhythmias. Developed by Alfonso Bueno-Orovio, Elizabeth Cherry, and Flavio Fenton in 2007, the model is a significant advancement in the understanding and simulation of complex heart rhythms.

Overview

The BOCF model is a simplification of the more complex Luo-Rudy model, which itself is a detailed representation of cardiac action potential. The BOCF model reduces the complexity by using fewer variables and equations, making it computationally more efficient while retaining the ability to accurately reproduce the electrical properties of cardiac cells under different physiological and pathological conditions.

Model Description

The Bueno-Orovio-Cherry-Fenton model incorporates four main variables that represent the gating variables and ionic concentrations affecting the cardiac cell's action potential. These include the transmembrane potential, a recovery variable, and variables related to the inflow and outflow of ions such as calcium and potassium. The equations in the BOCF model are formulated as ordinary differential equations (ODEs) that can be solved numerically to simulate the action potential propagation across cardiac tissue.

Applications

The primary application of the BOCF model is in the study and simulation of cardiac arrhythmias, such as atrial fibrillation and ventricular fibrillation. By adjusting the parameters of the model, researchers can explore how changes in cellular or tissue properties might lead to arrhythmogenic conditions. This model is also used in the development of anti-arrhythmic drugs and in the design of more effective defibrillation strategies.

Impact and Reception

Since its introduction, the Bueno-Orovio-Cherry-Fenton model has been widely adopted in both academic research and clinical studies. Its ability to balance computational efficiency with biological accuracy makes it a valuable tool in the field of computational cardiology.
