ABSTRACT The Nav1.5 channel, a major isoform of voltage‐gated sodium ion channel, is mainly found in ventricular cardiomyocytes, playing a key role in generating essential cardiac action potentials for normal heart rhythms. Mutations in Nav1.5 have been associated with severe heart conditions such as long QT syndrome, Brugada syndrome, cardiac ...

Postoperative delirium is linked to increased morbidity, mortality, and prolonged hospitalization; however, its short‐term consequences after major emergency abdominal surgery remain insufficiently studied. This prospective cohort study included 752 patients undergoing major emergency abdominal surgery at Copenhagen University Hospital, Herlev, from ...

Successful radiofrequency catheter ablation therapy of an adolescent with atrial ectopic tachycardia
Atrial ectopic tachycardia is an incessant supraventricular tachycardia and is frequently refractory to medical treatment. Because it can cause tachycardia-induced cardiomyopathy, early diagnosis and treatment is important.

Left Atrial Roof-Dependent Atrial Tachycardia Mimicking a Posterior Focal Atrial Tachycardia
A 77-year-old woman who had previously undergone pulmonary vein (PV) isolation for persistent atrial fibrillation underwent a second procedure for a recurrent atrial tachycardia (AT). The clinical AT was a dual-loop AT with left atrial (LA) roof-dependent and anterior macro-re-entrant circuits ...

Abstract Abnormalities in the heart's rhythm, known as arrhythmias, pose a significant threat to global health, often leading to severe cardiac conditions and sudden cardiac deaths. Therefore, early and accurate detection of arrhythmias is crucial for timely intervention and potentially life‐saving treatment.

Cardiac adrenergic control and atrial fibrillation [PDF]
Atrial fibrillation (AF) is the most common cardiac arrhythmia, and it causes substantial mortality. The autonomic nervous system, and particularly the adrenergic/cholinergic balance, has a profound influence on the occurrence of AF ...

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

BackgroundRadiofrequency ablation (RFA) for atrioventricular nodal reentrant tachycardia appears to reduce atrial tachycardia, which might relate to parasympathetic denervation at cardiac ganglionated plexuses.
