Molecular and clinical determinants of drug-induced long QT syndrome: an iatrogenic channelopathy. [PDF]
, 2004 More than 70 drugs present on the Swiss market can cause drug-induced long QT syndrome (LQTS), which is associated with torsades de pointes (TdP) arrhythmias, potentially leading to sudden cardiac death. Basic and clinical investigations performed during

926-24 Clinical and Electrophysiological Characteristics in Patients with Exercise Induced Idiopathic Multiform Ventricular Tachycardia. Differential Effects of Atrial Pacing and Isoproterenol Infusion on QTc Interval and Induction of Ventricular Arrhythmia [PDF]
, 1995 Idiopathic multiform ventricular tachycardia (VT) is characterized by normal QT interval at restand 3 or more distinct QRS configuration during VT, which has been distinguished from torsade de pointes in long QT syndrome.

QT Interval in Pregnant and Non-pregnant Women
Archives of Academic Emergency Medicine, 2018 Introduction: Prolongation of QT interval might result in dangerous cardiac arrhythmias, including Torsades de Pointes (TdP), consequently leading to syncope or death.

Correction of the QT Interval in Children.
Japanese Circulation Journal, 1995 We evaluated the usefulness of 11 formulas for correcting the QT interval in children, including the square root, cubic root, logarithmic, linear, exponential, and inverse formulas using the Mean-squared residual (MSR) values and Akaike Information Criterion (AIC) in 8,086 first-graders, 9,989 seventh-graders, and 5,786 tenth-graders. The subjects were

Electrocardiographic T-wave peak-to-end interval for hypoglycaemia detection. [PDF]
, 2010 Electrocardiographic T wave peak-to-end interval (TpTe) is one parameter of T wave morphology, which contains indicators for hypoglycaemia. This paper shows the corrected TpTe (TpTe(c)) interval as one of the inputs contributing to detect hypoglycaemia ...

Relationship between QT interval and ventricular electrical axis: A new suggestion for Lead selection in QT interval measurement [PDF]
Acta Medica Iranica, 2000 Exploration of the interlead QT variation (QT dispersion) introduced cardiologists to some new concepts including the deed to define a standard for lead selection in the measurement of QT interval and the reason or factors contributing to QT dispersion ...
