Why the study?
Does a 30-electrode array better discriminate changes in heterogeneity of repolarization compared to a 12-lead standard ECG in a rabbit heart model?
Population
Modified Langendorff-perfused rabbit heart model immersed in a cylindrical chamber
Comparison
QT interval dispersion measurement using an… vs QTID measurement using 12-lead standard ECG
Design
Preclinical

Multi-electrode arrays may enhance repolarization heterogeneity detection in animal models; leaves open translation to clinical ECG risk stratification.

A 30-electrode array better discriminates changes in repolarization heterogeneity compared to a standard 12-lead ECG in an in vitro rabbit heart model.
