Interplay of Probe Stability and Oscillation During Very‐High‐Power Short‐Duration Ablation in Pulmonary Vein Isolation for Atrial Fibrillation

Pacing and Clinical Electrophysiology, EarlyView.
This graphical abstract presents a comprehensive analysis of probe stability and oscillation during very high‐power short‐duration (vHPSD) pulmonary vein isolation (PVI) for atrial fibrillation. The findings indicate that oscillation velocity serves as a more reliable predictor of impedance drop and temperature changes than contact force alone ...

Prevalence and prognosis of patients with lone and paroxysmal atrial tachyarrhythmias showing Brugada-type electrocardiograms after class IC antiarrhythmic drug administration but no risk-stratifying factors

Journal of Arrhythmia, 2013
Background: Class IC antiarrhythmic drugs, used to prevent paroxysmal atrial tachyarrhythmias (ATs), are well known to effectively unmask the electrocardiogram (ECG) pattern of Brugada syndrome.

Intra‐Procedural Three‐Dimensional Rotational Angiography in Cryoballoon Ablation of Atrial Fibrillation: An RCT

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background The impact of various imaging techniques on the safety and outcomes of atrial fibrillation (AF) ablation remains unclear. Intra‐procedural three‐dimensional rotational angiography (3DRA) is the least used imaging method despite some benefits.

Safety issues of antiarrhythmic therapy for atrial fibrillation

Клинический разбор в общей медицине
The article discusses the safety of antiarrhythmic therapy for atrial fibrillation in the light of the development of cardiac and non-cardiac side effects, the presence of drug-drug interactions of antiarrhythmic drugs in the near (with anticoagulants ...

Management of monomorphic ventricular tachycardia electrical storm in structural heart disease

Journal of the Saudi Heart Association, 2019
Electrical storm (ES) is a life-threatening condition that is defined by three or more episodes of sustained ventricular tachycardia (VT), ventricular fibrillation (VF), or appropriate shocks from an implantable cardioverter defibrillator (ICD) within 24

Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Structure mirroring function: What's the ‘matter’ with the funny current?

The Journal of Physiology, EarlyView.
Abstract figure legend The ‘funny’ (If) current of cardiac pacemaker cells has been first identified in the late 1970s as a major mechanism in the generation and control of cardiac pacemaking. Decades of studies have since described the properties of the funny current and of its molecular components, HCN channels, in the heart and brain, providing the ...

The Role of Ranolazine in the Treatment of Ventricular Tachycardia and Atrial Fibrillation: A Narrative Review of the Clinical Evidence

Biomedicines
Cardiac arrhythmias are among the leading causes of morbidity and mortality worldwide. While antiarrhythmic drugs traditionally represent the first-line management strategy, their use is often limited by profound proarrhythmic effects.

Electromechanical modelling and simulation of human‐induced pluripotent stem cell‐derived cardiomyocytes predict drug‐induced contractility effects

The Journal of Physiology, EarlyView.
Abstract figure legend A study described in this paper describes a new tool for hiPSC‐CM electromechanical behaviour simulations using mathematical modelling. The model enables in silico assays making drug testing quick, comprehensive and accurate. New hiPSC‐CM models can be used as a platform to integrate in vitro and in silico findings.
