Intermittent Ventricular Pre‐Excitation: Clinical Features and Electrophysiological Properties

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Intermittent ventricular pre‐excitation has long been considered a low‐risk marker for sudden death. Accessory pathways (APs) with high‐risk intermittent antegrade conductive properties may exist, but this still represents a gray area in current guidelines.

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

The 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 ...

Conversion of supraventricular arrhythmias to sinus rhythm using flecainide [PDF]

, 2017
We evaluated the efficacy of flecainide acetate (given intravenously to a maximal dose of2 mg kg−1 and then orally in a dose of 100 mg b.d. or 100 mg t.d.s.) in the conversion to sinus rhythm of 50 patients exhibiting supraventricular arrhythmias (39 ...

Surgical management of children and young adults with the Wolff-Parkinson-White syndrome [PDF]

, 1988
The Wolff-Parkinson-White syndrome, as originally described, includes palpitations, tachycardia, and an abnormal electrocardiogram (short PR interval and wide QRS complex).

Heritability and causality of QRS duration and chronic heart failure risk

ESC Heart Failure, Volume 12, Issue 4, Page 3018-3027, August 2025.
Methodological framework used to investigate the heritability using linkage disequilibrium score regression (LDSC) and causal relationship between QRS duration (exposure) and chronic heart failure (outcome) using Mendelian randomization. QRS data were sourced from GWAS and exome‐wide association studies (EWAS), and chronic heart failure GWAS data were ...

Multiple Cardiac Rhabdomyomas, Wolff-Parkinson-White Syndrome, and Tuberous Sclerosis: An Infrequent Combination [PDF]

, 2014
Cardiac rhabdomyomas are benign cardiac tumours and are often associated with tuberous sclerosis. They are often asymptomatic with spontaneus regresion but can cause heart failure, arrhythmias, and obstruction. There have also been a few isolated reports

Extra‐cardiac vagal stimulation: Clinical utility of a novel diagnostic and therapeutic tool in supraventricular tachycardia

Journal of Arrhythmia, Volume 41, Issue 4, August 2025.
Extracardiac vagal stimulation (ECVS) is a novel, safe tool inducing controlled AV/VA block. It assists SVT differential diagnosis, pathway unmasking, and ablation endpoint confirmation, adding value to EP procedures for supraventricular tachycardias.
