Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Recognizing Pathogenic PVCs in Children: A Case of Multifocal Ectopic Purkinje-Related Premature Contractions

Case Reports in Pediatrics
Premature ventricular contractions (PVCs) are a common and benign arrhythmia in children, but they can infrequently be a sign of an underlying cardiac issue that may predispose patients to heart failure and/or sudden cardiac death (SCD).

3D Map Combined with Transthoracic Echocardiography for Ablation of Premature Ventricular Contractions/Ventricular Arrhythmia from Papillary Muscle: A Technical Report [PDF]

Ventricular arrhythmias originating from the papillary muscle of the ventricles are complex clinical problems. Catheter ablation has the potential to cure these arrhythmias.

Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

Short coupled premature ventricular contraction initiating ventricular fibrillation in a patient with Brugada syndrome.

, 2004
Patients with Brugada syndrome typically have ST segment elevation in ECG leads V1–V3, infrequent ventricular premature contractions with variable coupling intervals, inducible ventricular arrhythmia during electrophysiologic studies, and ventricular ...

hERG1 channels and potential therapeutics for long QT syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend Prolonged QT results from hERG1 channel dysfunction. (A) Physiological anterograde trafficking of hERG1 channels to the plasma membrane, leading to a normal electrocardiogram. (B) Prolonged QT results from the presence of fewer hERG1 channels on the plasma membrane due to decreased anterograde trafficking or reduced function due ...

Left ventricular dyssynchrony predicts the cardiomyopathy associated with premature ventricular contractions

, 2018
BACKGROUND The pathophysiology of cardiomyopathy associated with premature ventricular contractions (PVCs) remains unclear.OBJECTIVES This study prospectively explored cardiomyopathy development in a swine model of paced ectopic beats.METHODS A total of ...
