Effect of Flecainide on Multifocal Ectopic Purkinje-Related Premature Contractions in an R814W SCN5A Carrier

JACC: Case Reports
Multifocal ectopic Purkinje-related premature contraction (MEPPC) is an autosomal dominant SCN5A channelopathy characterized by frequent multiform premature ventricular contractions originating from the His-Purkinje system.

Hemodynamic consequences of premature ventricular contractions: Association of mechanical bradycardia and postextrasystolic potentiation with premature ventricular contraction-induced cardiomyopathy.

Heart Rhythm, 2019
BACKGROUND The relationships between hemodynamic consequences of premature ventricular contractions (PVCs) and development of premature ventricular contraction-induced cardiomyopathy (PVC-CM) have not been investigated.

Integrating Chain‐of‐Thought and Retrieval Augmented Generation Enhances Rare Disease Diagnosis From Clinical Notes

Medicine Bulletin, EarlyView.
ABSTRACT Background Several studies show that large language models (LLMs) struggle with phenotype‐driven gene prioritization for rare diseases. These studies typically use Human Phenotype Ontology (HPO) terms to prompt foundation models such as GPT and LLaMA to predict candidate genes.

Acute Cardiac Tamponade after Left Sided Premature Ventricular Contraction Ablation

Journal of Cardiovascular Emergencies, 2016
Introduction: Premature ventricular complex (PVC) is the most common cardiac arrhythmia, which in some circumstances can lead to syncope, arrhythmia-induced cardiomyopathy and sudden death.

The role of M cells and the long QT syndrome in cardiac arrhythmias: simulation studies of reentrant excitations using a detailed electrophysiological model

, 2004
In this numerical study, we investigate the role of intrinsic heterogeneities of cardiac tissue due to M cells in the generation and maintenance of reentrant excitations using the detailed Luo-Rudy dynamic model. This model has been extended to include a

Evolving Features of RASopathies Among Pregnancies With Abnormal Fetal Fluid Collections

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective We aimed to characterize the fetal features across gestation and describe genotype‐phenotype correlations for pregnancies with fetal RASopathies that were more severely affected as they presented with at least one abnormal fluid collection.

Adjuvant use of a cryoballoon to facilitate ablation of premature ventricular contraction–triggered ventricular fibrillation originating from the moderator band

HeartRhythm Case Reports, 2019
Effective ablation on the moderator band can be facilitated by intracardiac echocardiography to Introduction Idiopathic ventricular fibrillation (VF) may be initiated by short-coupled premature ventricular contractions (PVCs) originating from the ...

Idiopathic Epicardial Ventricular Arrhythmias: Diagnosis and Ablation Technique from the Aortic Sinus of Valsalva [PDF]

, 2005
Idiopathic outflow tract arrhythmias (ventricular tachycardias or symptomatic premature ventricular contractions; OT-VT/PVCs) can originate from the left ventricular (LV) epicardium (Epi-VT/PVCs), and radiofrequency (RF) energy applications from the ...
