Experimental recordings of transmural activation in the human left ventricle show variability in recorded activation times. In this paper we demonstrate a framework for fitting the conductivity tensor of a monodomain model to reproduce activation tim...

Evaluation of computational modelling as a preclinical proarrhythmic safety assay (2013)
Presentation / Conference Contribution
Mirams, G., Beattie, K., Cui, Y., Luscombe, C., Williams, G., Gavaghan, D., & McMahon, N. (2012, October). Evaluation of computational modelling as a preclinical proarrhythmic safety assay. Presented at Safety Pharmacology Society Annual Meeting, Phoenix, AZ

Many cardiac ion channels are prone to reduced current flow following blockade by pharmaceutical compounds. High throughput screening technologies now allow us to establish this reduction in activity routinely and relatively cheaply. It would be adva...

Introduction
Drugs that prolong the QT interval on the electrocardiogram present a major safety concern for pharmaceutical companies and regulatory agencies. Despite a range of assays performed to assess compound effects on the QT interval, QT prolo...

Introduction: Unwanted drug interactions with ionic currents in the heart can lead to an increased pro-arrhythmic risk to patients in the clinic. It is therefore a priority for safety pharmacology teams to detect block of cardiac ion channels, and ne...

PLoS ONE, 8(2), Article e56359. https://doi.org/10.1371/journal.pone.0056359

Differences in mRNA expression levels have been observed in failing versus non-failing human hearts for several membrane channel proteins and accessory subunits. These differences may play a causal role in electrophysiological changes observed in hum...
