Why Temporary Pacing in Acute Inferior Myocardial Infarction or No‐Reflow Becomes a Trigger—Not a Remedy—For Ventricular Fibrillation: Undersensing, “R‐On‐T”, Catheter Trauma and the Ischaemic Substrate

Annals of Noninvasive Electrocardiology, Volume 31, Issue 1, January 2026.
Temporary pacing during acute inferior MI can paradoxically trigger VF via four mechanisms; the authors advocate reversing ischaemia before inserting a wire. ABSTRACT Temporary pacing during acute inferior MI or no‐reflow can trigger ventricular fibrillation rather than prevent it. Four mechanisms are highlighted: (1) acute ischemia lowers VF threshold

Machine learning‐based prediction of atrial fibrillation in patients with atrial high‐rate episodes

European Journal of Clinical Investigation, Volume 56, Issue 1, January 2026.
Abstract Background Given the modest performance of available predictive models in estimating the risk of atrial fibrillation (AF) in patients with atrial high‐rate episodes (AHREs) detected by cardiac implantable electronic devices (CIEDs), this study explores the potential use of machine learning (ML) algorithms in this context. Purpose To assess the

Albumin, urea‐to‐albumin ratio, or the albumin‐to‐creatinine ratio to predict outcomes in heart failure with mildly reduced ejection fraction

European Journal of Clinical Investigation, Volume 56, Issue 1, January 2026.
Among 2061 hospitalized HFmrEF patients, low albumin, albumin‐to‐creatinine ratios (ACR), and elevated urea‐to‐albumin ratios (UAR) independently predicted long‐term all‐cause mortality, but not HF‐related rehospitalization. The UAR and ACR did not provide a clinically significant predictive advantage over albumin levels alone. Abstract Background This

Outcomes of Focused Double Extrastimuli Mapping and Ablation in Ventricular Tachycardia

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 1, Page 137-148, January 2026.
ABSTRACT Background Conventional substrate mapping for scar‐related ventricular tachycardia (VT) often fails to fully delineate critical arrhythmogenic components. Functional mapping strategies using extrastimuli have shown promise but are limited by procedural complexity.

Huge reduction of defibrillation thresholds using four electrode defibrillators

, 2014
In the absence of a better solution, ventricular fibrillation is treated by applying one or several large electrical shocks to the patient. The question of how to lower the energy required for a successful shock is still a current issue in both fundamental research and clinical practice.

Protective association of renin‐angiotensin system inhibitor use with skeletal muscle wasting in diabetic heart failure

Journal of Diabetes Investigation, Volume 17, Issue 1, Page 73-82, January 2026.
In heart failure, renin‐angiotensin system inhibitor (RASI) use was associated with less skeletal muscle wasting in patients with diabetes, but not in those without diabetes (significant interaction). The association in diabetes was more evident at lower plasma 3‐methylhistidine levels than at higher levels, suggesting a potential biomarker‐defined ...

Coronary Spasm Due to Pulsed Field Ablation: A State‐of‐the‐Art Review

Pacing and Clinical Electrophysiology, Volume 49, Issue 1, Page 43-51, January 2026.
ABSTRACT With the ever‐growing population of patients undergoing cardiac ablation with pulsed electric fields, there is a need to understand secondary effects from the therapy. Coronary artery spasm is one such effect that has recently emerged as the subject of further investigation in electrophysiology literature.
