Just a random "vagus nerve story". A while back, I started having weird heart flutters that turned out to be extra heartbeats (doctors call them PVCs and PACs). Sometimes I'd be fine for days or even weeks, but then they'd come back pretty bad. After a bit, I noticed these flutters were linked to what I ate, which seemed really strange. I couldn't figure out how my food could make my heart skip beats. I saw a bunch of heart doctors for almost a year before I found one who knew what was up. He told me I had something called "gastrocardiac syndrome." Apparently, not many heart doctors know about it. It's basically when acid reflux in your stomach messes with the vagus nerve. The doctor gave me some medicine to stop the acid (PPIs), and just like that, my weird heartbeats went away completely.
