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 ...

This page lists all known medications that could potentially lead to 'Electrocardiogram QT shortened' as a side effect. It's important to note that mild side effects are quite common with medications.

Case – A 30-year-old man with light-headedness, palpitations and syncopal episodes presents to his GP. On examination his ECG reveals atrial fibrillation (AF) but with frequent ventricular ectopics.

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 ...

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 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 ...

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 ...
