Diagnosis of long QT syndrome An EKG or ECG (Electrocardiogram) is often performed to test the electrical activity of the heart. Each heart beat entails generation of an electrical signal that ...

In long QT syndrome, the heart muscle takes longer than normal to electrically recharge after it contracts. A test called an electrocardiogram (also called an ECG or EKG) can detect this problem.

Long QT 2: The ECG shows low amplitude T waves frequently with a notch. Arrhythmias are more likely to occur during rest/sleep especially with sudden awakening and/or auditory stimuli.

Among patients with long QT syndrome but a normal resting QTc value, defined as less than 450 ms, the deep neural network distinguished long QT syndrome from normal with an AUC of 0.83 vs. 0.67 ...

Content Long QT syndrome (LQTS) is an inherited genetic disorder associated with QT prolongation on the electrocardiogram (ECG) and ventricular tachyarrhythmias that manifest as syncope, aborted ...

Long QT Syndrome is considered a rare condition. A person may inherit this condition or develop it at some point in their life. What happens is the heart beats in a fast and chaotic rhythm.

When someone has LQTS, it is noted on their ECG 60 percent to 80 percent of the time. In 20 percent to 40 percent of cases, the QT is normal (hidden or concealed LQTS), and it is only under ...

Why Choose University of Utah Health U of U Health has a long history of researching inherited arrhythmia. Researchers in our program identified the gene mutations that cause long QT syndrome. Our ...

Patients with congenital or other forms of long QT syndrome. Investigators recommend that these patients should be informed that drinking grapefruit juice in large quantities may impose some risk.

Long QT syndrome (LQTS) is a condition that affects the electrical activity of the heart. It is a rare condition and is most commonly inherited from first degree relatives.
