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 ...
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 QT interval on an electrocardiogram signifies the time required for the heart to repolarize after depolarization. It has long been appreciated that a long QT interval predisposes patients to ...
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 ...
A prolonged QT interval creates an electro-physiological environment that is favorable for the development of cardiac arrhythmias. A new study in Holland suggests that yet another group of ...
OBJECTIVE: To examine the effect of cisapride on the corrected QT (QTc) interval in infants over a 14-day period. STUDY DESIGN: A prospective cohort study of infants receiving cisapride (0.8 mg/kg per ...
A machine learning model was more effective at detecting congenital long QT syndrome on resting ECGs than manual measurement of QT intervals by arrhythmia experts, in a new study. Researchers ...
Researchers have discovered a new drug that may be useful in treating a heart rhythm condition called long QT syndrome. Johns Hopkins researchers have discovered a new drug that may be useful in ...
Objectives The short QT syndrome is a cardiac channelopathy characterised by accelerated repolarisation which manifests as a short QT interval on the ECG. The definition of a short QT interval is ...
