Actually I had the 270, but slightly different, called a Toupet. My wrap was sewn to the esophagus instead of to itself as in a full wrap. It stops the reflux but does not stop tachycardia from specific food triggers or esophageal or other GI irritation.
I still get tach if I eat anything containing sulfites, or from pills getting stuck in esophagus and irritating, gas bubble in the stomach, or more recently, from colon being irritated from an abscess forming and diverticulitis starting. The last one caused me to go to the ER after tach for 5 hours to get my heart reset. The GI connection to the heart is through the vagus nerve. There is something called cardio-esophageal reflex, or linked angina.
Have you seen a cardiologist about
this problem? Before blaming the GI tract you need to rule out a heart problem.
