Association of increased QTc interval with the cardiometabolic syndrome.

Recent studies indicate a high prevalence of increased QTc interval length in patients affected by the metabolic syndrome, but there is no data available to demonstrate the correlation of the QTc interval with severity of the cardiometabolic syndrome (CMS).

Electrocardiograms were collected from 1420 participants in a cross-sectional study.
