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 ...

Percutaneous Catheter Ablation of Epicardial Accessory Pathways. [PDF]

, 2017
Radiofrequency (RF) catheter ablation is the treatment of choice in patients with accessory pathways (APs) and Wolff-Parkinson-White syndrome. Endocardial catheter ablation has limitations, including the inability to map and ablate intramural or ...

Zero Fluoroscopy Ablation of Arrhythmias in Patients With Congenital Heart Disease

Journal of Arrhythmia, Volume 41, Issue 6, December 2025.
Zero‐fluoroscopy radiofrequency ablation using 3D electroanatomic mapping was performed in 42 patients with mild, moderate, or great complexity congenital heart disease. Acute success was 100%, with no complications and minimal recurrence over 48 months. This approach eliminates radiation exposure while maintaining safety and efficacy across select yet

Socioeconomic Status, Race, and Ethnicity in Management of Pediatric Supraventricular Tachycardia

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background An electrophysiology study (EPS) with ablation is often the preferred approach to management of supraventricular tachycardia (SVT) and/or preexcitation (Wolff‐Parkinson‐White syndrome) in children and adolescents.

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 ...

Wolff-Parkinson-White syndrome in an adolescent with depression [PDF]

, 2016
Wolff-Parkinson-White (WPW) syndrome is a congenital disorder characterised by a macro-reentrant arrhythmia caused by preexcitation of the ventricles.

Intermittent Ventricular Pre‐Excitation: Clinical Features and Electrophysiological Properties

Journal of Cardiovascular Electrophysiology, Volume 36, Issue 11, Page 2818-2826, November 2025.
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.

Anaesthetic management of emergency exploratory laparotomy for ruptured ectopic pregnancy in a patient with Ebstein’s anomaly and Wolff-Parkinson-White syndrome: a challenge for the anaesthesiologists [PDF]

, 2016
Ebstein's anomaly (incidence 1:110,000) is characterized by the downward displacement and elongation of the tricuspid valve with poorly contractile right ventricle, an enlarged right atrium along with tricuspid regurgitation.

Wolff-Parkinson-White syndrome with cleft lip and palate: A rare, previously unreported association

Journal of Indian Academy of Oral Medicine and Radiology, 2008
Wolff-Parkinson-White syndrome, also called Pre Excitation Syndrome, is characterized by an extra pathway that conducts the electrical impulses from the atria to the ventricles without the normal delay.
