Torsades de pointes (TdP) is a characteristic polymorphic ventricular arrhythmia associated
with delayed ventricular repolarization as evidenced on the surface electrocardiogram by QT …

Autonomic dysregulation in cardiovascular disease plays a major role in the pathogenesis of
arrhythmias. Cardiac neural control relies on complex feedback loops consisting of efferent …

Previous studies suggest an impact of dexmedetomidine on cardiac electrophysiology.
However, experimental data is sparse. Therefore, purpose of this study was to investigate …

Background Dexmedetomidine has controversial influence on cardiac electrophysiology.
The aim of this study was to explore the effects of dexmedetomidine on perioperative cardiac …

Dexmedetomidine (DEX) is a commonly used sedative agent with no or minimal effects on
breathing. DEX may also be beneficial in myocardial protection. Since the mechanisms of …

Long QT syndrome (LQTS) is a rare inherited channelopathy caused mainly by different
mutations in genes encoding for cardiac K+ or Na+ channels, but can also be caused by …

Sympathetic hyperactivation during tracheal intubation prolongs the QT interval and
increases the risk of arrhythmias. We investigated if dexmedetomidine pretreatment affected …

Background Persistent myocardial ischemia post-myocardial infarction can lead to fatal
ventricular arrhythmias such as ventricular tachycardia and fibrillation, both of which carry …

The duration of the QT interval as measured by 12-lead electrocardiography is a measure of
myocardial repolarization and is widely used to describe cardiac abnormalities, to determine …

Background This study was done to investigate how nicardipine, remifentanil and
dexmedetomidine affect the balance of the autonomic nervous system in patients receiving …
