[Rhythm management in patients with heart failure].

Introduction: Arrhythmias manifest frequently in individuals with heart failure, posing a notable threat of mortality and morbidity. While the prevention of sudden cardiac death through ICD therapy remains pivotal, accurate risk stratification remains a challenging task even in 2024. Recent data underscore the early consideration of catheter ablation for ventricular tachycardias. Although antiarrhythmic drug therapy serves as an ancillary measure for symptomatic patients, it does not confer prognostic advantages. The holistic management of arrhythmias in heart failure necessitates a systematic, multidimensional approach that initiates with evidence-based medical therapy for heart failure and integrates device-based and interventional therapies. Noteworthy clinical studies have illustrated the positive prognostic impact of early rhythm control strategies, particularly catheter ablation, in individuals managing heart failure and atrial fibrillation.
