099277 - COMPUTATIONAL BIOLOGY OF THE HEART
The main objective of this course is the detailed study of the mathematical models dscribing the ionic currents, the action potential of the different cells of the heart, and the models describing the propagation of the electric signal in the heart. The course look in detail the numerical solution of the resulting equations as well as the implementation in the computer favoring the interaction of the student with computer codes implemented in a user friendly environment. These modeling and simulation tools are then applied to the study of arrhythmias in particular those associated with acute regional ischemia.
