Cardiac Resynchronization Therapy: Reconsidering Its Essence as a Treatment for Electrical Dyssynchrony in Heart Failure

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
Flow of cardiac resynchronization therapy (CRT) in heart failure management. Heart failure (HF) patients with electrical dyssynchrony are first identified through screening. If electrical dyssynchrony contributes to HF deterioration, CRT is initiated to improve electrical synchrony.

A Novel Multiparametric Model Integrating Aortoseptal Angle to Predict the Origin of Outflow Tract Ventricular Arrhythmias

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
The aortoseptal angle (cutoff 131.24°) effectively differentiates ventricular arrhythmia originating from the left ventricular outflow tract (LVOT). Combining the aortoseptal angle with the hypertension status and V2 transition ratio significantly improves its diagnostic accuracy.

A Rare Case of RNRVAS Termination and Re‐Initiation Visualized on a 12‐Lead ECG

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
This case illustrates both termination and re‐initiation of repetitive non‐reentrant ventriculoatrial synchrony (RNRVAS) visualized on a standard 12‐lead ECG. It highlights how pacemaker algorithms such as VIP and PVC response, together with abnormal atrial refractoriness, can trigger or terminate RNRVAS.

Transient 7‐hour coma following a sacrococcygeal epidural with ropivacaine in a cat

Veterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract A 2‐year‐old cat was anaesthetised for pelvic fracture repair. Premedication included methadone 0.2 mg/kg and medetomidine 5 µg/kg intravenously (IV). Anaesthesia was induced with ketamine 2 mg/kg and propofol 1 mg/kg IV and maintained with isoflurane.

Suspected pro‐arrhythmic effects of flecainide and the limitations of in‐hospital short‐duration electrocardiography in detecting ventricular arrhythmia burden in a dog with dilated cardiomyopathy

Veterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract A 10‐year‐old, female, spayed Pitbull mix presented for evaluation of an arrhythmia. Echocardiography revealed enlargement of all cardiac chambers and decreased left ventricular systolic function. Electrocardiography demonstrated isolated, ventricular premature complexes.
