Realistic electrocardiogram (ECG) simulation with numerical models is important for
research linking cellular and molecular physiology to clinically observable signals, and …

As a potentially life threatening side effect, pharmaceutical compounds may trigger cardiac
arrhythmias by impeding the heart's electrical and mechanical function. For this reason, any …

State-of-the-art cardiac electrophysiology models that are able to deliver physiologically
motivated activation maps and electrocardiograms (ECGs) can only be solved on high …

Mathematical models of the electrophysiology of cardiac tissue play an important role when
studying heart rhythm disorders like atrial fibrillation. Model parameters such as conductivity …

Estimating tissue conductivity parameters from electrograms (EGMs) could be an important
tool for diagnosing and treating heart rhythm disorders such as atrial fibrillation (AF). One of …

Cardiac muscle cells can exhibit complex patterns including irregular behaviour such as
chaos or (chaotic) early afterdepolarisations (EADs), which can lead to sudden cardiac …

Impaired electrical conduction has been shown to play an important role in the development
of heart rhythm disorders. Being able to determine the conductivity is important to localize …

In this paper we consider the monodomain model of cardiac electrophysiology. After an
analysis of the well-posedness of the model we determine an asymptotic expansion of the …

Atrial fibrillation is a heart condition that causes an irregular and abnormally fast heart rate,
as well as a multifactorial and progressive cardiac disease with different manifestations in …

In this paper, we describe a monodomain model with a non-local source term that accounts
for any intra-or extracellular applied current, and specifically for the usual virtual electrode …
