What Happens When You Have Afib With A Pacemaker - Atrial fibrillation may return after cardiac ablation. If you have atrial fibrillation (afib), that means something’s not right with the electrical signals that trigger your heartbeat. Many patients with atrial fibrillation (af) have sinus node dysfunction with symptomatic bradycardia requiring pacemaker. In afib, the heart's upper chambers (atria) beat irregularly, causing the pacemaker to work harder to maintain a regular heartbeat. If this happens, another ablation or heart treatment may be recommended.
