The team Carmen develops mathematical models and numerical methods in order to simulate the propagation of the cardiac action potential, from the cellular scale to the scale of the body. It is part of the IHU LIRYC, the electrophysiology and heart modeling institute in Bordeaux. It collaborates actively with the clinical, imaging, cellular electrophysiology, and signal processing groups within ...
This work proposes an optimal control approach for the termination of re-entry waves in cardiac electrophysiology. The control enters as an extracellular current density into the bidomain equations which are well established model equations in the literature to describe the electrical behavior of the cardiac tissue. The optimal control formulation is inspired, in part, by the dynamical systems ...
Diagnosis of intraneural conditions can be revealed by a combination of clinical examination, electrophysiology, magnetic resonance imaging (MRI), and targeted fascicular biopsy with subsequent microscopic analyses.
• Although voltage clamp methods have been applied experimentally to cardiac tissue for over a decade, this field of study has failed to achieve general acceptance because of limitations of the experimental approach and difficulty in interpreting the results. Yet this technique is valuable within its limitations, and to dismiss it would be to lose a valuable tool. In perspective, most technique...
The eld of cardiac electrophysiology has grown and changed dramatically since the last guideline on fellowship training objectives was published in 1988. Not only has the ability to diagnose arrhythmic diseases improved, but also the knowledge of genetic contributions and mechanisms of these disorders has expanded. Moreover, the treatment of these arrhythmias, including ablation and implantab...
AIMS To assess the diagnostic yield of the head-up tilt test and electrophysiology in different groups of patients with syncope of unknown origin established according to simple clinical criteria. METHODS AND RESULTS Six hundred consecutive patients with syncope of unknown origin submitted to a tilt test. Two hundred and forty seven of them also underwent electrophysiology. Patients were divi...
