Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

The FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

Catheter Ablation: Evolution and Efficiencies

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT The present review includes a discussion the goals and pitfalls of efficiency in the medical profession, a historical perspective on the evolution of catheter ablation in the field of electrophysiology (EP), and the data regarding the relationship between efficiency and outcomes in the EP lab. Focus on efficacy is critical to maximize resource

Pulseless Ventricular Tachycardia

Pulseless ventricular tachycardia is a life-threatening cardiac arrhythmia in which coordinated ventricular contractions are replaced by very rapid but ineffective contractions, leading to insufficient organ perfusion and heart failure.

Long‐Term Serial Exercise Stress Testing in Catecholaminergic Polymorphic Ventricular Tachycardia on Beta‐Blocker and Flecainide Therapy

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a potentially life‐threatening arrhythmic disorder typically treated with beta‐blockers and, occasionally, with flecainide. Methods All patients underwent genetic testing, electrocardiogram, echocardiogram, and exercise testing.

The V6R/V4R Index: A Novel ECG Parameter for Identifying Idiopathic Ventricular Arrhythmias Originating From the Aortic Cusp

Journal of Cardiovascular Electrophysiology, EarlyView.
The V6R/V4R amplitude index is a novel and practical electrocardiographic parameter for identifying idiopathic ventricular arrhythmias originating from the aortic cusp. A cutoff >0.55 accurately distinguishes cusp from adjacent non‐cusp origins within the left ventricular outflow tract, facilitating targeted mapping and procedural planning.

Safety and Utility of Smartphone‐Based Heart Monitors in Pediatric Patients With Cardiovascular Implantable Electronic Devices

Journal of Cardiovascular Electrophysiology, EarlyView.
Smartphone heart monitors in pediatric CIEDs: A pilot study. Smartphone heart monitors did not induce EMI in children with CIEDs, enabling reliable heart rate measurement and accurate identification of ventricular non‐captures. ABSTRACT Background Portable heart monitors enable on‐demand electrocardiogram (ECG) recordings and enhance symptom‐rhythm ...
