Longer QTc may signal arrhythmia risk in subclinical hyperthyroidism; leaves open need for prospective outcome studies.
Does subclinical hyperthyroidism prolong ventricular repolarization measured by QTc compared to healthy controls?
Subclinical hyperthyroidism is associated with prolonged ventricular repolarization (QTc), suggesting a potential mechanism for increased arrhythmia risk in these patients.
Owecki et al. (2006) studied this question.
