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 ...

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 ...

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) ...

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 ...

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 ...

A heart arrhythmia is when your heart beats too fast, too slow, or out of sync. Some arrhythmias can be genetic. A genetic arrhythmia happens when one or both of your parents pass down a gene change ...

Congenital long QT syndrome (LQTS) is caused by mutations in genes encoding cardiac ion channels, and is characterized by prolongation of the ventricular cardiac action potential, which lengthens the ...

ANN ARBOR, Mich.---You're sitting at your desk and suddenly your heart is beating in overdrive or worse, lurching along like a car on fumes. It is a shocking, uncomfortable and frightening sensation.

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 ...
