Long QT and short QT syndromes (LQTS and SQTS) are cardiac repolarization
abnormalities that are characterized by length perturbations of the QT interval as measured …

Several antipsychotics are associated with the ventricular tachycardia torsade de pointes
(TdP), which may lead to sudden cardiac death (SCD), because of their inhibition of the …

Block of the hERG potassium channel and prolongation of the QT interval are predictors of
drug‐induced torsade de pointes. However, drugs that block the hERG potassium channel …

Abstract Background: Both the Tpeak‐Tend interval (Tp‐e) and the Tp‐e/QT ratio have been
linked to increased risk for arrhythmia. Patient Tp‐e/QT ratios were investigated prior to …

INTRODUCTION: The Tpeak-Tend interval (TpTe) has been linked to increased arrhythmic
risk. TpTe was investigated before and after primary percutaneous coronary intervention …

Background Recently a new risk marker for drug‐induced arrhythmias called index of cardio‐
electrophysiological balance (iCEB), measured as QT interval divided by QRS duration, was …

Patients with loss-of-function mutations in KCNQ1 have KCNQ1 long QT syndrome (LQTS).
KCNQ1 encodes a voltage-gated K+ channel located in both cardiomyocytes and pancreatic …

INTRODUCTION: Reference values for T-wave morphology analysis and evaluation of the
relationship with age, sex, and heart rate are lacking in the literature. In this study, we …

Introduction: Although antipsychotics have been associated with sudden cardiac death
(SCD), they still remain a cornerstone in the treatment of psychiatric patients. Most …

Cardiovascular diseases are the main causes of mortality. Sudden cardiac death may also
appear in athletes, due to underlying congenital or inherited cardiac abnormalities. The …
