[Corrected QT interval and corrected QT interval dispersion is worthwhile when interpreted with other repolarization measurements].
We read the article entitled ‘‘The effect of esmolol on corrected-QT interval, corrected-QT interval dispersion changes seen during anesthesia induction in hypertensive patients taking an angiotensin-converting enzyme inhibitor’’ by Ceker et al. with interest.1 The authors investigated the effects of esmolol on the hemodynamic, correctedQT (QTc) interval and corrected-QT interval dispersion (QT...
متن کاملEffects of methadone on QT-interval dispersion.
STUDY OBJECTIVE To evaluate the effects of methadone on QT-interval dispersion. DESIGN Single-center, prospective, cohort study. SETTING Methadone maintenance treatment facility. PATIENTS One hundred eighteen patients who were newly admitted to the facility. Intervention. Twelve-lead electrocardiograms (ECGs) were performed in patients at both baseline and 6 months after the start of meth...
متن کاملQT Dispersion and T Wave Peak–to–end Interval Dispersion in Children with Kawasaki Disease
BACKGROUND 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 we...
متن کامل[The long QT interval syndrome].
The syndrome of long QT interval frequently follows to syncope or a sudden cardiac death on the basis of originated polymorphic ventricular tachycardia of the "torsade de pointes" type. The prolongation of the QT interval in the hereditary form is based on mutation of the genes responsible for the formation of sodium and potassium channels. The authors analyze the occurrence, clinical findings,...
متن کاملCorrection of the QT interval in children.
We evaluated the usefulness of 11 formulas for correcting the QT interval in children, including the square root, cubic root, logarithmic, linear, exponential, and inverse formulas using the Mean-squared residual (MSR) values and Akaike Information Criterion (AIC) in 8,086 first-graders, 9,989 seventh-graders, and 5,786 tenth-graders. The subjects were divided into six groups according to age a...
