Prognostic Value of Spatial Trajectory of J‐Point Amplitude Across Left Precordial Leads in a Community‐Based Population

Annals of Noninvasive Electrocardiology, Volume 31, Issue 5, September 2026.
In NHANES III adults, latent class trajectory analysis identified a J‐point phenotype characterized by higher V4 amplitude and a steep decline toward V6. This spatial trajectory was independently associated with increased long‐term all‐cause mortality and cardiac death, suggesting prognostic value beyond conventional early repolarization criteria ...

Emergency zero-fluoroscopy catheter ablation for refractory ventricular tachycardia in third-trimester pregnancy: a case report

Frontiers in Cardiovascular Medicine
BackgroundThe incidence of symptomatic arrhythmias during pregnancy has markedly increased in recent years. Atrial fibrillation/flutter and life-threatening ventricular arrhythmias are of particular concern due to their association with elevated maternal

Idiopathic Fascicular Ventricular Tachycardia [PDF]

, 2004
Idiopathic fascicular ventricular tachycardia is an important cardiac arrhythmia with specific electrocardiographic features and therapeutic options. It is characterized by relatively narrow QRS complex and right bundle branch block pattern. The QRS axis

Thromboembolism in a Patient with a Left Ventricular Aneurysm

Eurasian Journal of Emergency Medicine, 2016
Idiopathic aneurysms involving the left ventricle are considered very rare, and in a majority of instances, they are asymptomatic. In a minority of patients, they may present with cardiac rupture, cardiac tamponade, ventricular arrhythmias, and sudden ...

Do K_ATP channels open as a prominent and early feature during ischaemia in the Langendorff-perfused rat heart? [PDF]

, 2000
The objective was to investigate whether myocardial adenosine triphosphate-sensitive K⁺ (K_ATP) channels open during the first 10 min of regional ischaemia in Langendorff-perfused rat hearts.

Usefulness of Galectin-3 as a Biochemical Marker to Detect Ventricular and Supraventricular Arrhythmias in Children

Current Issues in Molecular Biology
Galectin-3 (Gal-3) has been demonstrated to play a pivotal role in the pathogenesis of several fibrotic disorders. A number of studies have examined the relationship between galectin-3 levels and cardiac fibrosis in heart failure.

Emergency catheter ablation in critical patients

Journal of Emergencies, Trauma and Shock, 2010
Emergency catheter ablation is justified in critical patients with drug-refractory life-threatening arrhythmias. The procedure can be used for ablation of an accessory pathway in preexcitation syndrome with high risk of ventricular fibrillation and in ...
