T-Wave Oversensing In Subcutaneous Defibrillators

A subcutaneous implantable cardioverter-defibrillator (S-ICD) protects patients from sudden cardiac death without placing a transvenous lead inside the heart.…

Atrial Fibrillation Ablation in Obese Patients: Weight Loss as Adjunctive Therapy

Obesity is increasingly recognised as a modifiable driver of atrial fibrillation (AF), rather than a background characteristic that simply complicates…

Implantable Cardioverter-Defibrillator Decisions in Nonischemic Cardiomyopathy

Implantable cardioverter-defibrillators (ICDs) remain an important strategy for preventing sudden cardiac death in selected patients with nonischemic…

Biatrial mapping in persistent atrial fibrillation: new insights into drivers

Persistent atrial fibrillation (AF) is often treated as a disorder sustained by several interacting mechanisms rather than a single, stable source. Electrical…

Antitachycardia pacing for ventricular tachycardia in cardiac sarcoidosis

Cardiac sarcoidosis can create a difficult combination of myocardial inflammation, patchy fibrosis, conduction disease and ventricular arrhythmia. Ventricular…

Pacemaker-mediated tachycardia: diagnosis and prevention

Pacemaker-mediated tachycardia (PMT) is a rapid, usually regular rhythm produced by an interaction between a dual-chamber pacemaker and the patient’s own…

Electrocardiographic Changes in Hyperkalemia and Arrhythmia Risk

Hyperkalemia is a common and potentially reversible cause of conduction disturbance, bradyarrhythmia, ventricular tachycardia and cardiac arrest. Its…

Remote magnetic navigation for ventricular tachycardia ablation: comparative outcomes

Ventricular tachycardia (VT) ablation is technically demanding because the arrhythmogenic substrate may be extensive, intramural, epicardial, or difficult to…

Contact force sensing in atrial fibrillation catheter ablation

Atrial fibrillation affects roughly 460,000 Australians and accounts for over 60,000 hospital admissions every year, driving stroke and heart failure and…

Subcutaneous ICDs in Young Patients With Congenital Heart Disease

Subcutaneous implantable cardioverter-defibrillator technology has matured into a mainstream option for adults at risk of sudden cardiac death, but its role in…
