Po-685-07 area weighted unipolar voltage to predict heart failure death in patients with ischemic cardiomyopathy and ventricular tachycardia
Heart Rhythm(2022)
摘要
Patients with ischemic cardiomyopathy (ICM) referred for catheter ablation (CA) of ventricular tachycardia (VT) are at risk for end-stage heart failure (HF) due to adverse remodeling of the left ventricle (LV). Local unipolar voltages (UV) decrease with loss of viable myocardium. A UV mapping derived parameter that corrects for oversampling of the infarct area may reflect the total amount of remaining LV viable myocardium.
