Redefining atrial fibrillation treatment success: patient-defined goals for arrhythmia burden and health-related quality of life

Background: Despite the use of atrial fibrillation (AF) cutoff of 30s as the standard for success in most AF clinical trials, patients consider an AF Severity Scale (AFSS) of ≤ 5 or AF duration ≤ 1 hour as treatment success. Prevalence and factors associated with these patient-de...

Revisiting low-voltage interpretation: Chamber-specific relationships between myocardial wall thickness and omnipolar voltage

Electrogram voltage reflects multiple factors, including viable myocardial mass, structural integrity, electrode configuration, catheter orientation, and activation sequence. How local myocardial wall thickness (WT) contributes to voltage amplitude in structurally intact myocardi...
