Efficacy of Additional Extra Mapping‐Guided Substrate Ablation Beyond Pulmonary Vein Isolation in Persistent Atrial Fibrillation: The Rotate Trial

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction There are currently no established effective additional substrate ablation strategies beyond pulmonary vein isolation (PVI) for persistent atrial fibrillation (AF). Objective This randomized clinical trial evaluated the efficacy of a novel substrate ablation technique using the ExTRa Mapping system, which visualizes rotational ...

Voltage‐Gradient Mapping‐Guided Slow Pathway Ablation in Typical Atrioventricular Nodal Re‐Entrant Tachycardia

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction High‐density mapping is useful for common atrioventricular nodal re‐entrant tachycardia (AVNRT) ablation. This study aimed to evaluate the effective targets for slow pathway (SP) ablation using voltage‐gradient mapping. Methods Fifty‐two patients diagnosed with slow/fast AVNRT were enrolled.

An unusual WPW syndrome: What is the preexcitation variant?

Indian Pacing and Electrophysiology Journal, 2015
A 15-year-old female with WPW syndrome and normal heart underwent an electrophysiology study for paroxysmal palpitations and syncope. Intravenous adenosine produced an unexpected response of QRS changes and advanced AV block.

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 ...

Atrioventricular Nodal Re-entry Tachycardia in Identical Twins: A Case Report and Literature Review

Indian Pacing and Electrophysiology Journal, 2013
This report details the case of 17 year old identical twins who both presented with paroxysmal supraventricular tachycardia (PSVT). Electrophysiological studies revealed atrioventricular nodal reentry tachycardia (AVNRT) in both twins.

Clinical feasibility of high‐power short‐duration strategy at the sites adjacent to the esophagus during laser balloon‐based pulmonary vein isolation

Journal of Arrhythmia, Volume 41, Issue 4, August 2025.
We enrolled 50 ablation sites (12, 10, 8.5, and 5.5 W) in 11 patients where the esophageal temperature reached 39°C within 5 s after ablation. Although ablation duration was correlated with power settings, total energy and maximal esophageal temperature did not differ significantly among the 4 groups.
