We attempted to evaluate whether subjects who exhibit prolonged corrected QT (QTc) interval (≥440 ms in men and ≥460 ms in women) on ECG, with and without ECG-diagnosed left ventricular hypertrophy (ECG-LVH; Cornell product, ≥244 mV×ms), are at increased risk of stroke. Among the 10...
Objective To evaluate the effect of diabetic ketoacidosis (DKA) on the QT interval corrected for heart rate (QTc) in children. Ketosis occurs in several conditions, including DKA and alcoholic ketoacidosis, and during use of very low-carbohydrate diets. Prolongation of the QTc has been described ...

Among the 501 patients included (mean age 65 years; mean left ventricular ejection fraction 33.1%), longer paced ventricular conduction was associated with longer baseline QRS duration, longer QT interval, and lower ejection fraction. On multivariable analysis, longer paced QRS duration was associated...
3A. Phenanthrene caused a significant (p < 0.05) dose-dependent prolongation of the corrected QT interval of the ECG (Fig. 3B). Phenanthrene prolonged QTc from 336.6 ± 8.9 ms in unexposed animals to 413.8 ± 10.4, 432.8 ± 49.9, and 471 ± 52 ms in 0.5, 1.0 and 1.5 mg L−1, ...
Surface ECGs of TASK-1−/− mice revealed a significant prolongation of the rate corrected QT interval. Telemetric ECG recordings for 24 h, during physical and pharmacological stress testing and after ischemia/reperfusion injury did not result in a higher incidence of arrhythmias. Infarct size ...
