Task: Question Answering
Input (English): Context: The main complication of Kawasaki disease is the Coronary Artery (CA) involvement and long term follow up of patients depends on the severity of coronary arterial aneurysms, ischemia, and thrombosis. Early diagnosis of these complications can lead to a more desirable outcome for patients. Myocardial ischemia can prolong QT dispersion and increase the risk of cardiac arrhythmias as well as sudden cardiac arrests. Also, T wave peak-to-end (Tp-Te) interval dispersion, which provides a valuable index of transmural dispersion of repolarization, can trigger the arrhythmia.', "We evaluated the non-corrected QT interval dispersion (QTD) and the corrected QT (QTc) dispersion and measured Tp-Te interval dispersion in 49 Iranian children (28 males and 21 females) with the diagnosis of Kawasaki disease (KD) in the acute phase and 49 age-matched controls in a prospective study from 2009 to 2012. Student's t-test and Pearson correlation were used to analyze the data. All the statistical analyses were performed through the SPSS 16. Besides, P<0.05 was considered as statistically significant.", 'Patients with KD had significantly longer QTc dispersion (0.099±0.055 s versus. 0.040±0.018 s; P<0.001), non-corrected QT dispersion (0.075±0.046 versus 0.042±0.019; P<0.001), and Tp-Te dispersion (0.047±0.054 versus 0.022±0.011; P=0.015). The patients with elevation in white blood cell count (above 15000) had a statistically significant increased in QTD (P=0.011). No significant correlation was found between coronary involvement and repolarization indexes.\Question: Do qT Dispersion and T Wave Peak-to-end Interval Dispersion in Children with Kawasaki Disease?
Output (English): In conclusion, the QT interval (corrected or non-corrected) and the Tp-Te dispersion significantly increased in the patients with KD which shows repolarization changes during the acute phase of KD. However, there is no correlation between the QT interval and the coronary involvement.
