This study presents a novel approach combining left bundle branch area pacing with defibrillation support for a patient with heart failure and ventricular tachycardia. This innovative technique aims to prevent cardiac death and improve ventricular function by mitigating pacing-induced dyssynchrony.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Device Technology
Background:
- Heart failure with reduced ejection fraction (HFrEF) poses significant risks, including sudden cardiac death from ventricular arrhythmias.
- Conventional right ventricular pacing can exacerbate left ventricular dysfunction in HFrEF patients.
- Biventricular pacing is recommended for HFrEF with conduction disorders but may induce dyssynchrony in patients with narrow QRS.
