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 ...

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 ...

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 ...

ROTTERDAM, the NETHERLANDS — A new analysis of participants in a population-based cohort study suggests at least two ECGs might be useful to stratify individuals at risk for sudden cardiac death (SCD) ...

A simple electrocardiogram (ECG) can pinpoint hospitalized COVID-19 patients at high risk of death who might need intensive management. That's the finding of a study presented at EHRA 2022, a ...

MOUNTAIN VIEW, Calif., May 10, 2018 /PRNewswire/ -- AliveCor, the leader in artificial intelligence and FDA-cleared personal electrocardiogram (ECG) technology, today announced an important milestone ...

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 ...

The QRS complex is irregular and coarse "fibrillatory waves" are present (see atrial fibrillation review by clicking below) indicating the presence of atrial fibrillation. There is quite a slow ...

Treatment of long QT syndrome (LQTS) aims to prevent sudden cardiac death and similarly fatal abnormal heart rhythms and fainting spells. LQTS is a genetic condition in the majority of cases and ...

Copenhagen, Denmark – 4 April 2022: A simple electrocardiogram (ECG) can pinpoint hospitalised COVID-19 patients at high risk of death who might need intensive management. That’s the finding of a ...
