Initiation of ventricular arrhythmia in the acquired long QT syndrome. [PDF]
Cardiovasc Res, 2023 Aims Long QT syndrome (LQTS) carries a risk of life-threatening polymorphic ventricular tachycardia (Torsades de Pointes, TdP) and is a major cause of premature sudden cardiac death.

The diagnostic role of T wave morphology biomarkers in congenital and acquired long QT syndrome: A systematic review. [PDF]
Ann Noninvasive Electrocardiol, 2023 QTc prolongation is key in diagnosing long QT syndrome (LQTS), however 25%–50% with congenital LQTS (cLQTS) demonstrate a normal resting QTc. T wave morphology (TWM) can distinguish cLQTS subtypes but its role in acquired LQTS (aLQTS) is unclear.

Acquired long QT syndrome due to antiemetics, COVID-19 and Blastocystis hominis induced exacerbation of congenital chloride losing diarrhoea. [PDF]
BMJ Case Rep, 2022 Congenital chloride losing diarrhoea (CCLD) is a rare disease caused by mutations in an intestinal chloride/bicarbonate ion exchange channel. Few reports describe CCLD in adults and none has described the impact of a parasitic infection on CCLD.

In Vitro and In Silico Risk Assessment in Acquired Long QT Syndrome: The Devil Is in the Details [PDF]
Frontiers in Physiology, 2017 Acquired long QT syndrome, mostly as a result of drug block of the Kv11. 1 potassium channel in the heart, is characterized by delayed cardiac myocyte repolarization, prolongation of the T interval on the ECG, syncope and sudden cardiac death due to the ...
