Syncope with QT‐interval prolongation and T‐wave inversion in anterior and inferior leads: Foreboder of a life‐threatening condition?

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
The patient’s ECG exhibited QT‐interval prolongation with T‐wave inversion in anterior and inferior leads that, together with CT‐pulmonary angiography findings, strongly suggested PE. This ECG pattern is crucial for diagnosing PE. Abstract Even though patients with pulmonary embolism usually present with respiratory distress and tachycardia, the ...

Microvolt T‐wave alternans in early repolarization syndrome associated with ventricular arrhythmias: A case report

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Microvolt T‐wave alternans (MTWA) is a marker for the development of ventricular arrhythmias (VA), but its role in early repolarization (ER) syndrome remains unknown. MTWA was detected in a 90‐second 6‐lead electrocardiogram from an ER syndrome patient. On average, MTWA was 50 μV, higher than what was observed on healthy subjects.

Genetic association study of QT interval highlights role for calcium signaling pathways in myocardial repolarization. [PDF]

, 2013
The QT interval, an electrocardiographic measure reflecting myocardial repolarization, is a heritable trait. QT prolongation is a risk factor for ventricular arrhythmias and sudden cardiac death (SCD) and could indicate the presence of the potentially ...

The diagnostic role of T wave morphology biomarkers in congenital and acquired long QT syndrome: A systematic review

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Numerous T wave morphology biomarkers, which can supplement QTc assessment in long QT syndrome (LQTS), have been identified. Their diagnostic capabilities include differentiation of genotypes, identification of concealed LQTS, differentiating acquired LQTS from congenital LQTS; and determining multichannel versus hERG channel blockade.

Update on long QT syndrome [PDF]

Journal of Cardiovascular Electrophysiology, 2019
AbstractLong QT syndrome (LQTS) is an inherited disorder characterized by a prolonged QT interval in the 12‐lead electrocardiogram and increased risk of malignant arrhythmias in patients with a structurally normal heart. Since its first description in the 1950s, advances in molecular genetics have greatly improved our understanding of the cause and ...

New Linear Codes as Quasi-Twisted Codes from Long Constacyclic Codes [PDF]

, 2020
One of the most important and challenging problems in coding theory is to determine the optimal values of the parameters of a linear code and to explicitly construct codes with optimal parameters, or as close to the optimal values as possible. The class of quasi-twisted (QT) codes has been very promising in this regard.
