A: Adjusted mean corrected QT (QTc) values, 3B: Adjusted mean QRS values, 3C: Adjusted mean JTc values, for patients with and without cardiac involvement (positive troponin or B-natriuretic peptide [BNP]). Troponin and BNP were evaluated separately. Multivariable analysis was controlled for age, gender, body mass index, history of diabetes mellitus, hypertension, premature ventricular contractions, atrial fibrillation/flutter, ventricular tachycardia, QT prolonging medications, potassium level and QRS duration when applicable.
