The QT interval on an ECG is a vital marker of heart health, but measuring and interpreting it correctly can be tricky. Advances in formulas, regulatory guidance, and AI-powered tools are helping ...

In this study, we describe the overlapping phenotypes of short QT interval with Brugada-like ECG in a Chinese man. Furthermore, we identify a heterozygous missense mutation in the patient′s SCN5A ...

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 ...

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 ...

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 ...

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 ...

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) ...

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 ...
