The Spatial Ventricular Gradient Is Associated with Pacing-Induced Cardiomyopathy.
Heart Rhythm
December 2024
Harvard-Thorndike Electrophysiology Institute, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA. Electronic address:
Background: Pacing-induced cardiomyopathy (PICM) is a frequent complication of right ventricular pacing that often requires re-operation for biventricular or conduction system pacing. Better methods for predicting PICM may inform initial pacing strategy and follow-up monitoring.
Objective: To determine if the spatial ventricular gradient (SVG), a vectorcardiographic marker of ventricular electrical and mechanical heterogeneity, is associated with subsequent development of PICM.
Measurement of Tip Load With a Pacemaker Lead Stylet and Guiding Catheter Using a Silicone Heart Model.
Cureus
November 2024
Cardiology, Akita Cerebrospinal and Cardiovascular Center, Akita, JPN.
Background Ventricular septal pacing has long been performed using a stylet during pacemaker implantation, but with the availability of guiding catheters, His bundle pacing and left bundle branch area pacing have also been performed. However, it is not known to what extent the tip load of the ventricular lead differs when a guiding catheter is used compared with a stylet alone. In this study, the tip load was measured for different stylet stiffness and guiding catheter geometries at sites where His bundle pacing and left bundle branch area pacing were assumed.

Background: Ventricular arrhythmia is a common type of arrhythmia observed in clinical practice. It is primarily characterized by premature ventricular contractions, ventricular tachycardia, and ventricular fibrillation. Abnormal formation or transmission of cardiac electrical impulses in patients affects cardiac ejection function.

Premature ventricular contractions (PVCs) are a common finding in patients with surgically repaired congenital heart defects including transposition of the great arteries (D-TGA). While often asymptomatic, PVCs can sometimes lead to palpitations, dyspnea, and hemodynamic compromise, requiring therapeutic intervention. The arterial switch operation is the preferred treatment for D-TGA, but these patients have a 2% incidence of ventricular arrhythmias and 1% incidence of sudden cardiac death post-operatively.

Department of Internal Medicine, Division of Cardiovascular Medicine, Spencer Fox Eccles School of Medicine, University of Utah, Salt Lake City, UT.
Introduction: Hospitalization rates for acute decompensated heart failure (ADHF) have increased, resulting in 6.5 million hospital days annually. Despite this, optimal diuretic strategies for managing ADHF remain unclear, highlighting the need to analyze diuretic practice patterns in ADHF treatment.
