QT interval, cardiovascular risk factors and risk of death in diabetes. We still do not know why QT interval is prolonged and how this abnormality leads to death. Nevertheless, QT interval is a simple, low-cost measure, ... M Veglio,A Chinaglia,P Cavallo-Perin - 《Journal of Endocrinologi...
What conditions or situations cause prolonged QT intervals in the electrocardiogram besides the use of antidepressants? If there is a need for an antiarrhythmic in a patient on an antidepressant, which antiarrhythmics are less likely to cause further prolongation of the QT interval?. ...
Although a QT interval of at least 500 milliseconds generally has been shown to correlate with a higher risk of torsades de pointes, there is no established threshold below which prolongation of the QT interval is considered free of proarrhythmic risk. The risk of torsades de pointes should be...

(0.26 sec) compared with the PR intervals of the other sinus complexes. Because every third QRS complex is a PVC, this is ventricular trigeminy. The QT/QTc intervals are normal (400/400 msec and 360/360 msec when the prolonged QRS complex duration is considered)....
