Trigger versus Substrate: Multi-Dimensional Modulation of QT-Prolongation Associated Arrhythmic Dynamics by a hERG Channel Activator [PDF]
Background: Prolongation of the QT interval of the electrocardiogram (ECG), underlain by prolongation of the action potential duration (APD) at the cellular level, is linked to increased vulnerability to cardiac arrhythmia.

214 Gene-specific effect of beta-adrenergic blockade on QT duration in the Long QT syndrome [PDF]
BackgroundIn the long QT syndrome (LQTS) the clinical efficacy of beta-blocker treatment differs according to the genotype. We aimed to asses the effect of beta-blocker treatment in LQT1 and LQT2 patients.Patients and methods24-hour Holter ECG were ...

Haloperidol affects coupling between QT and RR intervals in guinea pig isolated heart
Prolonged QT interval is an independent risk factor for development of ventricular arrhythmias. Haloperidol is one of the drugs inducing QT prolongation.

The electrocardiography (ECG) QT interval is influenced by fluctuations in heart rate (HR) what may lead to misinterpretation of its length. Considering that alterations in QT interval length reflect abnormalities of the ventricular repolarisation which ...

Torsades de pointes induced by garenoxacin in association with pacing failure in an elderly woman with VDD pacemaker [PDF]
SummaryAn 86-year-old woman was admitted to the hospital for syncope and convulsion 4 days after starting antibiotic therapy for pneumonia with oral garenoxacin 400mg/day. She had a VDD pacemaker for complete atrioventricular (AV) block.
