Hi, I've seen 2 cases that mentioned the AV node recovery. I'm not sure it was partially or completely? They both already had a pacemaker. These are for after few years ablation. This is not what the EP and patient wants, isn't it? The aim for AV node ablation is hopefully terminated the conduction permanently.
Are you surprising about you have a complete heart block after the AV node ablation?
You may do better with a "subject" such as: AV node recovery or Recovery from AV ablation injury (if either of these is in fact what you are seeing information on).
This will bump you to the top in any case so you'll get more page 1 exposure.
Sorry I can't help.
