Atrial fibrillation (AFib) is an irregular, often rapid heart rhythm that can lead to poor blood flow to the body. Managing the ventricular rate, the speed at which the heart’s ventricles contract and pump blood, is a primary goal in AFib treatment. Clinicians aim for a specific range of heartbeats per minute to optimize blood circulation and minimize symptoms like fatigue, shortness of breath, and lightheadedness. For instance, a common goal is to maintain a resting rate below 110 beats per minute, though individual patient needs may vary.
Effective rate control is essential for improving the quality of life for individuals with AFib. It can reduce the risk of stroke and heart failure, and allow patients to engage in daily activities with greater comfort and less limitation. Historically, rate control was primarily achieved using medications such as beta-blockers and calcium channel blockers. More recently, other strategies like ablation procedures have emerged as additional options for managing rapid ventricular rates.
