Genetics of cardiac repolarization

Svati H Shah et al. Nat Genet. 2009 Apr.

Abstract

Prolongation of the electrocardiographic QT interval, a measure of cardiac repolarization, is associated with arrhythmogenic disorders and is a risk factor for sudden cardiac death. Two genome-wide association studies (GWAS) of variation in the QT interval in population-based cohorts now report association with variants in a subset of ion channel genes and other new associations.
