Wide QRS Tachycardia in WPW: When Antidromic AVRT Imitates VT

Clinical Case Reports
Atrioventricular Re‐entry Tachycardia (AVRT) occurs in patients with accessory pathways (AP) via a re‐entry circuit between the AV node and the AP. Anterograde conduction through the AP causes antidromic AVRT with wide QRS complexes, which may mimic ...

Mitral regurgitation and decompensated heart failure in a young pregnant pony mare: An aetiological challenge

Equine Veterinary Education, Volume 38, Issue 10, Page e676-e685, October 2026.
Summary A 4‐year‐old, 6‐month pregnant, Welsh pony mare presented with severe acute clinical signs including depression, anorexia, pale mucous membranes, tachycardia with a grade 4/6 holosystolic murmur and moderate expiratory dyspnoea with diffuse wheezes. There was no evidence of placentitis or fetal distress.

Effects of cardioneuroablation for vasovagal syncope: ganglionated plexus localization by tentative anatomical ablation and high-frequency electrical stimulation

BMC Cardiovascular Disorders
Background Cardioneuroablation is increasingly being adopted as a treatment for vasovagal syncope (VVS). Identification of the cardiac ganglionated plexus (GP) is a critical factor influencing the outcome of the procedure.

Impact of Leadless Pacemaker Implantation Position on Subclinical Right Ventricular Perforation

Pacing and Clinical Electrophysiology, Volume 49, Issue 10, Page 1447-1454, October 2026.
ABSTRACT Introduction Leadless pacemakers are typically implanted in the mid‐septum of the right ventricle (RV) to mitigate the risk of perforation. However, reports on the precise location of these implants are limited. This study aimed to elucidate tine‐based leadless pacemaker position and presence of subclinical RV perforation through computed ...

Preclinical evaluation of reversible pulsed electrical field: electrophysiological and histological assessment of myocardium

Frontiers in Cardiovascular Medicine
BackgroundPulsed field ablation, as a non-thermal ablation modality, has received increasing attention. The aim of this study is to explore whether a reversible pulsed electric field (RPEF) can temporarily inhibit electrical conduction and provide a ...
