Does permanent His bundle pacing improve echocardiographic measurements, NYHA classification, and reduce diuretics use in atrial fibrillation patients with narrow QRS and heart failure undergoing atrioventricular node ablation?
Permanent His bundle pacing post-atrioventricular node ablation improves echocardiographic parameters, NYHA class, and reduces diuretic use in AF patients with heart failure and narrow QRS.
BACKGROUND: Clinical benefits from His bundle pacing (HBP) in heart failure patients with preserved and reduced left ventricular ejection fraction are still inconclusive. This study evaluated clinical outcomes of permanent HBP in atrial fibrillation patients with narrow QRS who underwent atrioventricular node ablation for heart failure symptoms despite rate control by medication. METHODS AND RESULTS: <0.001) when compared to the baseline diuretics use. CONCLUSIONS: Permanent HBP post-atrioventricular node ablation significantly improved echocardiographic measurements and New York Heart Association classification and reduced diuretics use for heart failure management in atrial fibrillation patients with narrow QRS who suffered from heart failure with preserved or reduced ejection fraction.
