Clinical Outcomes After Catheter Ablation in Patients With Structural Heart Disease and Ventricular Fibrillation

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction In patients with ischemic cardiomyopathy (ICM), recurrent VF may be treated with catheter ablation by targeting triggering premature ventricular complexes (PVCs) and/or ventricular scar homogenization. Data on optimal ablation strategies in patients with non‐ischemic cardiomyopathy (NICM) remain limited.

Exercise-induced left septal fascicular block: an expression of severe myocardial ischemia [PDF]

, 2006
The electrocardiogram (ECG) criteria for the left septal fascicular block (LSFB) are not universally accepted and many other denominations can be seen in literature: focal septal block, septal focal block, left septal fascicular block, left anterior ...

Anatomical Determinants of the Left Atrial Electrograms: Wall Thickness and Myocardial Fat Infiltration

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Electrogram peak‐to‐peak voltage depends on atrial wall structure and mapping configuration. We evaluated the relationship between computed tomography–derived atrial wall thickness, intramyocardial fat, myocardial muscle thickness, and electrogram voltage obtained with omnipolar, bipolar, and unipolar mapping.

Comparison of electrophysiological left bundle branch pacing characteristics in different bilateral electrode pacing vector configurations

Frontiers in Cardiovascular Medicine
IntroductionLeft bundle branch pacing (LBBP) in bipolar pacing with anodal capture produces a more balanced ventricular activation than conventional unipolar pacing but need high pacing output.

Feasibility, Safety, and Efficacy of Pulsed Field Ablation for Ventricular Arrhythmias: Insights From a Large Health System Registry in the United States

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Pulsed field ablation (PFA) is an emerging non‐thermal ablation modality with proven safety in atrial arrhythmia ablation. However, data on its performance for ventricular arrhythmias (VA) remain limited. Objective To evaluate the feasibility, safety, and efficacy of PFA for complex VA in a multicenter real‐world US registry ...

Focus on right ventricular outflow tract septal pacing [PDF]

, 2013
SummaryExperimental and clinical studies have shown that right ventricular apical pacing may result in long-term deleterious effects on account of its negative impact on left ventricular remodeling through desynchronization.

Loss of capture of conduction system pacemaker caused by fibrosis surrounding the lead: a case report

BMC Cardiovascular Disorders, 2023
Background Conduction system pacing (CSP) is a novel technique that involves pacing the His-Purkinje system instead of the traditional right ventricular (RV) apex.
