I’ve been doing vagal stim of my right costa conchae daily since March. I credit it with helping me reduce my afib episodes from weekly to once every 3.5 weeks. My PV were ablated in May, no afib since, but if I skip vagal stim I have a lot more PACs. I use an ear clip, ultrasound gel, tens device at 20 hz in my right ear for about 30 minutes. I can usually tell when it’s time to stop. I do it before bed. Cheap, easy and effective for me. I can provide references and links to what I use if anyone is interested. My heart rate is always bradycardic, vagal stim at the intensity I use doesn’t decrease it. I monitor it to make sure. I definitely had vagal triggers for my afib, but I think my pulmonary veins were the instigators. It is a lot easier and safer to do the PVs. I asked my EP to map me prior to ablating but I don’t think he did, at least I couldn’t find any tracings in my medical records. My heart is SO MUCH BETTER after my ablation.
