Objective: Multifocal atrial tachycardia (MAT), characterized by an irregularly irregular rhythm, is often regarded as a clinical imitator of atrial fibrillation (AF). We aimed to evaluate the prevalence of MAT misclassification as AF in the emergency department (ED) setting.
Methods: A retrospective analysis of 1,828 ECGs from patients discharged with AF diagnoses over five years.

Catheter ablation has emerged as a first-line therapy for many arrhythmias. However, data on the safety and outcomes of catheter ablation in the elderly population remain limited. Here, we aimed to study the outcomes of catheter ablation in octogenarians.

Sinoatrial node (SAN) dysfunction often accompanies supraventricular tachyarrhythmias such as atrial fibrillation (AF), which is referred to as tachycardia-bradycardia syndrome (TBS). Although there have been many studies on electrical remodeling in TBS, the regulatory mechanisms that cause electrical remodeling in the SAN and atrial muscles by chronic bradycardia or tachycardia have not yet been fully investigated. Here we hypothesized Pitx2c, a transcription factor that played a central role in the late aspects of left-right asymmetric morphogenesis, regulated an interrelationship between the SAN and the atrial muscles and was involved in TBS-like pathology.

Background: Common cocaine-induced arrhythmias include tachyarrhythmias such as sinus tachycardia, supraventricular tachycardia, and atrial fibrillation. Most studies evaluating cocaine toxicosis in canines have been performed in an experimental setting, using intravenous administration of the drug. Though helpful, these studies cannot be directly extrapolated in a clinical setting given the different routes of administration.

Atrial myxomas are the most common primary cardiac tumors. In 20% of cases, they arise from the right atrium. Only a few such tumors are reported to have arisen from the inferior vena cava.
