Atrial Fibrilation ablation surgery or Pacemaker

Just recently been diagnosed with AF. Medications to slow heart rate and blood thinner. I have breathing difficulties occasionally throughout the day. Where I have to lay down for 10 mins. My caradiologist wants to perform an ablation surgery but there's no guarantee it will fix and a second ablation surgery maybe required. Another alternative is as Pacemaker. Has anyone had the ablation surgery more than once and ended up having a pacemaker.
I'm 72. All I know is I can't wait for 8 months I need something now.
I'm meeting with medical consultant and heart nurse next week. What we questions should I ask. Thanks.
