I found this discussion fascinating. Stress plays a big part in AF - physical stress from over exercise or injury and emotional/psychological stress - and there’s a close link between stress and inflammation.
After my last ablation I had a lot of inflammation and my EP said it was my body, through my immune system, fighting very hard to heal itself.
This podcast is quite long at 1 1/2 hours. I love listening to podcasts when I’m out on my walk or driving (using Bluetooth).
