QT interval prolongation due to disorders of ventricular repolarization results in long QT syndrome (LQTS), which has been extensively investigated. In contrast, little is known about QT interval ...

Baltimore, MD - A large-scale genomic study has identified a new gene associated with abnormal QT intervals. The gene, known as NOS1AP, was not previously known to modulate cardiac repolarization, but ...

Findings in Nature Genetics support the idea that balance between sodium and potassium are essential to the heart. An international group of scientists identified 10 genes connected to changes in QT ...

A cardiologist at Saint Louis University School of Medicine was the first to identify a new hereditary condition that increases the risk of sudden cardiac death. The risk factor - a dramatic, short ...

ST. LOUIS---A cardiologist at Saint Louis University School of Medicine was the first to identify a new hereditary condition that increases the risk of sudden cardiac death. The risk factor - a ...

Using a new genomic strategy that has the power to survey the entire human genome and identify genes with common variants that contribute to complex diseases, researchers at Johns Hopkins, together ...

The QT interval is the time from the beginning of the QRS complex, representing ventricular depolarization, to the end of the T wave, resulting from ventricular repolarization. The normal QT interval ...

Aim To determine factors affecting the QT interval in athletes and find an improved means of QT correction (QTc) Method Data was gathered from the CAYA (Cardiovascular Assessment in Young Athletes) ...
