Post-infarction ventricular tachycardia (VT) is usually the clinical expression of a mature ventricular scar. Following myocardial infarction, surviving…
Pediatric pacing presents a distinctive engineering and clinical problem. A child may depend on a lead for many decades, while the heart, venous system,…
A cerebral infarction is often classified as cryptogenic when standard evaluation fails to identify a convincing source. Yet the absence of documented atrial…
Pulmonary vein isolation (PVI) with a cryoballoon has become an established treatment for symptomatic atrial fibrillation, particularly in patients with…
Atrial fibrillation (AF) and thyroid disease frequently intersect in clinical practice. Excess thyroid hormone can increase atrial automaticity, shorten atrial…
Complex atrial tachycardias often arise in patients whose atrial anatomy and conduction have been altered by prior ablation, surgery, structural heart disease,…
Cardiac resynchronization therapy (CRT) can improve ventricular function, symptoms, and survival in selected patients with heart failure and electrical…
Implantable cardioverter-defibrillators (ICDs) prevent sudden cardiac death by recognizing dangerous ventricular tachyarrhythmias and delivering…
Catheter ablation has traditionally relied on fluoroscopy to show catheter position, guide transseptal access, and confirm lead or sheath movement. Advances in…
Leadless pacing has moved from a niche alternative to an established option for selected patients who need ventricular support without a transvenous lead or…
