The QT interval is the time from the beginning of the QRS complex (ventricular depolarization) to the end of the T wave (ventricular repolarization). The normal QT interval is controversial and ...
The maternal heart significantly adapts to the circulatory needs of pregnancy, but the effect of pregnancy on ventricular repolarization is poorly understood. The aim of this study was to quantify ...
What is the best way to estimate the QT interval on the ECG? What is the equation for QTc? A good way to estimate if the QT interval prolonged is by checking its relation to the R-R interval. If the ...
Boston, MA - Patients who receive high doses of the antidepressants citalopram or escitalopram could potentially develop QT-interval prolongation, a marker of a slight increased risk for ventricular ...
