Abstract :
Hyperthyroidism is a highly prevalent disease affecting over 4 million people in the US. The disease is associated with many
cardiac complications including atrial fibrillation and also less commonly with ventricular tachycardia and fibrillation. Many cardiac
pathologies have been extensively studied; however, the relationship between hyperthyroidism and rate of ventricular repolarization
manifesting as a prolonged QTc interval is not well known. Prolonged QTc interval regardless of thyroid status is a risk factor for
cardiovascular mortality and life-threatening ventricular arrhythmia.The mechanism regarding the prolongation of the QT interval
in a hyperthyroid patient has not been extensively investigated although its clinical implications are relevant. Herein, we describe a
case of prolonged QTc in a patient who presented with signs of hyperthyroidism that was corrected with return to euthyroid status.
