New year, New challenges!

Difficult roads often lead to beautiful destinations...

I am a little bit late but since It’s my first post this year : I wish you all a happy new year may you be healthy and safe the whole year through. These are difficult times for all of us but now we can see the light at the end of the tunnel so let’s hope for the best. 

Luckily I had a joyful holiday with my family and close friends. It really feels so good to take a break at the end of the pandemic year. I couldn’t imagine a greater way to say goodbye to 2020 rather than a quiet spot by the sea, a sunny day and fresh air.

Speaking of challenges, the few previous weeks we have been working on the eikonal model in order to reproduce reentry. 

Reentry is an abnormal electrical wave that is looping back upon itself, it is responsible for the majority of arrhythmias. Included among these arrhythmias are atrial fibrillation, atrial flutter and atrioventricular nodal reentry. 

This can be, perfectly, reproduced with the reaction-diffusion models : The bidomain and monodomain models are widely used in electro cardiology; they define the electrical activity of the heart but unfortunately are computationally very expensive which is not adequate for clinical use. 

The eikonal model, on the other hand, only simulates the time at which a front wave reaches a given point and, therefore, leads to much faster computations. But the question is, can we have it all? 

I will let you know more in my next posts.

Till next time, take care of yourself and your close. 🙏
