What is a goal of rhythm control strategies in patients with heart failure and atrial fibrillation?

The goal of rhythm control strategies in patients with heart failure and atrial fibrillation is primarily aimed at improving left ventricular function and quality of life. Atrial fibrillation can adversely affect hemodynamics and lead to deterioration in heart function due to loss of effective atrial contraction and rapid ventricular rates. By restoring normal sinus rhythm through various interventions, rhythm control can improve cardiac output and enhance the heart's efficiency. Consequently, this not only helps in optimizing left ventricular function but also positively impacts the patient's overall quality of life, reducing symptoms such as fatigue and dyspnea.

While managing heart rate and potentially reducing hospitalizations are important aspects of care in atrial fibrillation, they are secondary benefits that result from achieving effective rhythm control. Improving exercise tolerance also follows as a potential benefit, but the primary focus remains on enhancing overall cardiac performance and the patient's experience of their condition, which underscores why improving left ventricular function and quality of life stands out as a principal goal.
