However, a pacemaker can be useful in some cases of atrial fibrillation by allowing the cardiologist to use medications for the atrial fib that might otherwise slow the heart rate to dangerous levels. Also, many people with atrial fibrillation have episodes when their heart rates get too low sometimes, and a pacemaker can be useful in preventing this from happening. Thus, many patients with atrial fib end up getting a pacemaker. I hope this answers your question. I wish your mother the best of luck.
