Just out of interest I would like to know how many of you out there also have acid reflux problems particularly associated with a hiatus hernia. I have a hiatus hernia and take omeprazole daily. I have researched this and fine that inflammation of the oesophagus can affect the left atrium. Also omeprazole deletes the body of magnesium, potassium and vitamin b12. I therefore take supplements and half abanana daily and now rarely have any episodes. I still take a beta blocker but this did not stop the episodes until I started with the supplements. I wear a fitbit chargeHR and check my pulse several times a day so would be aware of irregular heartbeats. Please respond if you also have reflux ...I have no other 'triggers " for AF.
