Repolarization adaptation to rapid change in heart rate in human models – a review

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

Computational modelling of the pro‐ and antiarrhythmic effects of atrial high rate‐dependent trafficking of small‐conductance calcium‐activated potassium channels

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Small‐conductance calcium‐activated potassium (SK) channels are important for atrial repolarization and can be targeted for atrial‐specific antiarrhythmic treatments. We developed a computational model with a calcium sensor to study the effects of increased pacing rate (5 Hz), which enhances SK‐channel gating and forward ...

Clinical Practice Guidelines for paroxysmal supraventricular tachycardia.

open access: yesMedisur, 2009
Clinical Practice Guidelines for paroxysmal supraventricular tachycardia. These are arrhythmias in which structures placed above the bifurcation of the bundle of His are involved; characterized by tachycardia with abrupt starting and ending.

Atrial fibrosis in atrial fibrillation: Mechanisms, mapping techniques and clinical applications

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Summary of key aspects of atrial fibrosis in atrial fibrillation, highlighting atrial fibrosis as a hallmark of atrial fibrillation (AF). (1) Different types of fibrosis (blue), illustrating reparative and reactive fibrosis; (2) fibrosis detection techniques (green), illustrating late gadolinium enhancement cardiac magnetic ...

The coexistence of Wolff-Parkinson-White syndrome (WPW) and atrioventricular nodal reentrant tachycardia (AVNRT)

open access: yesTurkish Journal of Emergency Medicine, 2018
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common type of reentrant paroxysmal supraventricular tachycardia that occurs in the presence of dual AV nodal physiology.

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

Experience with propafenone for the treatment of cardiac arrhythmias in children

open access: yesThe Turkish Journal of Pediatrics, 1990
The aim of this prospective study was to evaluate the efficacy of propafenone in suppressing various arrhythmias in a group of children who were patients in the Pediatric Cardiology Unit of Hacettepe University Children's Hospital. Seven of the 13
